HP Mini 5101
Intel stable drivers (xf86-video-intel-stable) from AUR will give you 250-290 FPS on glxgears.
Typical Intel HD Audio. Just follow alsa setup.
Make sure you have the latest version of alsa-utils, alsa-lib and alsa-firmware.
Works out of the box. (Guess it's because of HAL)
Broadcom (Wireless) Driver
$ lspci | grep Broadcom 08:00.0 Network controller: Broadcom Corporation Device 4353 (rev 01)
Using broadcom-wl from AUR will do the trick.
It may be necessary to load the driver manually: Template:File
Suspend on Lid
This here works quite fine: Suspend to RAM#Automatic Suspend, the Hard Way
It might be necessary to use "/etc/acpi/events/lm_lid" instead of "/etc/acpi/events/lid". (laptop-mode?)
Just change the "LID" to it's actual value. For me it was C1D0.
