HP Compaq NX6325
This article describes specific steps to configure hardware on the notebook model HP Compaq NX6325.
This notebook comes with the notorious BCM4312 wireless chip. Using ndiswrapper is my preferred method as it proved to be more reliable than fwcutter. However, the Windows driver from the HP website does not work. Instead, you can download the driver package from here: 
(yes it's called bcm4310).
Follow the wireless how-to to configure wireless with ndiswrapper.
Cpufreq, acpi and pm-utils work on this notebook. Please refer to the respective wiki articles on how to configure them:
When using ndiswrapper and pm-suspend or pm-hibernate, you need to create a hook to unload/load the ndiswrapper module on suspend (otherwise wireless will not work upon resume).
#!/bin/bash case $1 in hibernate) modprobe -r ndiswrapper ;; suspend) modprobe -r ndiswrapper ;; thaw) modprobe ndiswrapper ;; resume) modprobe ndiswrapper ;; *) echo "somebody is calling me totally wrong." ;; esac
Depending on what method/tool you use to connect wireless networks, you might have to include other commands in the above scripts or manually reconnect to the wireless network.
Audio & Video
Sound works fine, just follow the ALSA how-to.
For 3D graphics, the ATI Catalyst proprietary driver works. Please note that I have not tried the open source driver, so it might work.
Fingerprint, card slots, etc.
As it is the case with other Linux distributions, the fingerprint reader and the card reader are currently not supported.
