Networking

Ethernet

Bringing the ethernet up pass by using a >2.6.34 kernel which provides experimental support for ATL1C module

CONFIG_NETDEV_1000=y
CONFIG_ATL1C=m

Wireless

Wireless device use the Atheros 9k module by linux-wireless. It's working well.

CONFIG_WLAN=y
CONFIG_ATH_COMMON=m
CONFIG_ATH9K_HW=m
CONFIG_ATH9K_COMMON=m
CONFIG_ATH9K=m
CONFIG_ATH9K_DEBUGFS=y

X.org

Xorg works well, take the AGPgart, Xfree4.1 support in device drivers / graphic drivers. go for i915, and activate also modsetting
then emerge xf86-video-intel, xf86-input-synaptic, xf86-input-evdev, xf86-input-keyboard, xk86-input-mouse xorg-server

CONFIG_AGP=y
CONFIG_AGP_INTEL=m
CONFIG_VGA_ARB=y
CONFIG_VGA_ARB_MAX_GPUS=16
CONFIG_DRM=y
CONFIG_DRM_KMS_HELPER=m
CONFIG_DRM_I915=m
CONFIG_DRM_I915_KMS=y
CONFIG_VIDEO_OUTPUT_CONTROL=m
CONFIG_FB=y
CONFIG_FIRMWARE_EDID=y

Sound

Sound works well, tested w/ pulseaudio too, without any trouble.
Code: lsmod (relevant modules)

snd_hda_codec          62114  1 snd_hda_intel

Kernel Config

So drawing a clean & "match only what's needed" kernel setup is possible:

not yet perfect

Cleaning troubles

USB

Toshiba seems to provide a different ACPI, putting a noapic parameter into grub is the key for USB, wireless & more to work
Trying nolapic leads you into having *only one* core awakened.

ACPI

Wireless

wireless works well in WPA/WPA2 mode as soon as noapic/nolapic is used, not tested in WEP,Nosec but it wouldn't be a problem imho.

Final troubles

the shutdown [-r|-h] just hang into
