Got a HP Pavilion tx2550 toucscreen / tablet laptop ;)

Got a new laptop ;) a HP Pavilion tx2550eg touchscreen laptop / tablet pc.

Progress so far:
ACPI does not work
ati-drivers (closed source) working with xorg-server <=1.5.0 only (1.5.0 is xorg 7.4 which is not supported yet) currently running xorg-server 1.4.2
sound is intel hda which only works so far with model=acer (auto does give mixer, but no sound) unfortunately it does not disable speakers when plugging in a headset (chipset is ALC268)
onboard lan RealTek 8169 (module r8169) working.
WLAN Broadcom 432b chip supposedly detected by broadcom non-OSS driver, but doesn't let me set ESSID and doesn't seem to work ...
touchscreen/pen problems currently prolly cuz wacom driver does not support those devices USB according to page. will investigate.
fingerprint reader *should* work, but didn't try yet
webcam detected and driver loaded .. will test that today.
bluetooth and IRDA still to try
haven't tested the card readers yet but should be able to do that soon too...
