ASUS Eee PC 1215N
This page includes general information regarding Asus EEE PC 1215n and related notes on installing/using Arch Linux on it.
CPU: Intel Atom D525 1.83GHz 667 MHz CPU, 1MB L2 Cache
RAM: 2GB 1066MHz DDR3
HDD: 250/320GB 5400RPM
GPU: nVidia ION2 with Optimus (see below)
Display: 12.1" 1366x768 LED display
Wireless: Broadcom BCM4313 802.11 b/g
Card Reader: TODO
Extras: Two USB 3.0 ports, Bluetooth 3 (optional)
Wireless and Bluetooth
PS : With the new Kernel (3.0+) there is no need for any of the procedure below, because Wireless and Bluetooth work out of box ^^
Wireless: In order to use Wireless with the BCM4313 (Linux Kernel 3.0+) you need to blacklist bcmia by editing your /etc/modprobe.d/modprobe.conf and add this :
# blacklist bcma
Then restart and you can now use your BCM4313 normally :D
Bluetooth: BCM4313 --> Install packages to manager Bluetooth like "bluez", "bluez-firmware".
# sudo pacman -S bluez bluez-firmware
And then activate them by adding the bluetooth to the Daemons of the "/etc/rc.conf" configuration file.
# sudo nano /etc/rc.conf
And then add to bluetooth to the Daemons:
# DAEMONS=(... bluetooth)
Restart the all thing, so you can use the Bluetooth and/or the Wireless
For more information about installing and configuration bluetooth, take a look at the "Arch Linux Bluetooth Wiki".

nVidia ION 2 with Optimus
nVidia Optimus is basically a software configuration that utilizes an Intel IGP + an nVidia GPU that writes to the Intel IGP's framebuffer. This is all done on the software side. The nVidia GPU is not wired to the outputs (VGA, HDMI etc.) At the time of this writing (September 27, 2010) Optimus on Linux sucks (i.e. doesn't work at all). You can still use the Intel IGP, but there is no way to access the discrete GPU. DO NOT try to install the nVidia binary driver, you have been warned.
Things are not that bad however. There is a kernel module called "acpi_call" which enables you to power off the nVidia GPU, hence you can significantly improve battery life.
David Airlie seems to be working on PRIME support (google it). You can also try "bumblebee-git" from the aur, which is the first working soloution to get the nvidia-card besides the intel gpu working.
Module auto-detection may load the nouveau module, but this sometimes seems to cause X to crash after boot-up, so try blacklisting this module if you encounter this problem.
Update 1 : There is a new project, called Bumblebee (Transformers reference) that allows you to use the Nvidia Optimus ION2, but not natively, you have to instale it, and then call each program on the terminal with a command... (see more informations here and here)
http://aur.archlinux.org/packages.php?ID=48866 (AUR for Bumblebee)

Nvidia graphic card
On the default kernel (2.6.36 branch) you cannot suspend system after disabling nvidia card with "acpi_call" module (nor after turning it on once you disabed it). This bug affects also turning off laptop (you'll have to manually power off laptop with power button). Using LTS 2.6.32 kernel ("kernel26-lts" package) allows you to safely power off/suspend netbook with disabled nvidia card (but with older kernel you won't be able to use some eee Fn hotkeys: disabling LCD/external output, volume controls, playback controls).
Update (after a little testing):
With the latest kernel running (3.0) and the "acpi_call" module installed from AUR, the suspend and hibernate scripts used by pm-utils will work (from commandline and in Gnome 3) as long as the acpi_call module is added to the suspend modules list used by the scripts.
Turning on bluetooth freezes the system. Need to do hard reset. No more info about this atm.
CPU power consumption
There is a kernel parameter which must be added in linux 3.0 kernel to use energy saving feature of the intel driver:
pcie_aspm=force i915.i915_enable_rc6=1, see this thread.
