Touchscreen and stylus working - yay

Finally got the touchscreen and Stylus to work (duno about eraser part but that's not that important to me ;))
I had to install linux-2.6.27-rc7 for this to work. for some reason this gives me a total of 11 /dev/input/event* devices instead of the total of 5 before but whatever it works.
One other reason why I tried the kernel was cuz I wanted to use both cores of my CPU (2.6.26-gentoo-r7 didn't detect the 2nd core - I checked out the kernel source and it had to do with some bios(?) cpu map ... ) and to have ACPI working as well :)
On a side-note ACPI now works (battery percentage + automatic power off when shutting down)
I had to write patches for the ati-drivers to compile with 2.6.27 (simple ones, which I'll put on gentoo bugzilla and - if i find out where/how - give to ati ... One problem is though that the newest Catalyst 8.9 (8.532) does *not* work on my machine .. it keeps crashing X with some error about atiddxShadow or something .. so I downgraded to 8.8 (8.522) again and modified the patch I wrote to work with that too :) .. Haven't tried any wine games since then but I'm using the same gfx driver ... on the bright side .. Never Winter Nights is cool with a pen :D

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...

HP Pavillion tx 2550eg & Gentoo

I reported some bugs on gentoo bugzilla. Will still write a page/blog/wiki about the whole thing but if someone is looking for info now .. there it goes:

linux kernel 2.6.27(rc7) smp function changes + patches for ati-drivers
ati-drivers-8.532 - catalyst 8.9 crash
linuxwacom 0.8.1 with usb tablet support

Attached is my xorg.conf - non-cleaned up and in it's complete mess with vesa drivers as well as ati-drivers (for when i messed up ati-drivers hehe)

One thing that helped me a lot was the usb tablet pc support tracker entry on the linuxwacom SF.net tracker

P.S.: still working on that screen rotation but that is a minor issue for me since everything else works now :)
Oh and still haven't tested IrDA, bluetooth or the card readers yet .. not v important to me i guess ;)
