some 2.6.39 experiences (SD card worked! suspend and sound still broken...)

Timo Juhani Lindfors
Hi,

today I tried the shr-2.6.39-nodrm branch of
git://gitorious.org/shr/linux with my debian system.

I can finally boot with rootfs on SD card! Also usbhost works now, and
wifi (omhacks rfkill support is coming soon!).

There are still some issues though. For some reason sound card seems to
appear only very randomly. Also resume just shows a blinking cursor in
top left corner and then watchdog kills the system.

More minor issues are that I can't find current_now node or "temp"
(temperature) node for battery.
