You'll also need the firmware:

root #emerge --ask linux-firmware

You will also need to rename firmware files, see bug #351295.

2.6.38 kernel driver is capable of seriously spamming syslog with "Short CCK" messages. This was patched for 2.6.39, but hasn't been backported as of 2.6.38.7.

Sound Chip

  • Works under alsa using the HDA driver. Codec is Conexant.

Webcam

  • Works using uvcvideo driver.

Card Reader

  • Is a PCI device. SD Card portion works using SDHCI driver.

Fingerprint reader

  • Untested

WiFi, HDD LEDs

  • HDD LED works
  • WIFI LED blinks very rarely, not sure whats going on

Problems

  • thermal zone driver seems to be confused and fan seems to turn on way too often and too early
