I happen to have this exact tablet pc myself. I've installed Ubuntu Hoary (Breezy doesn't work very well and i'm too lazy to fiddle. Breezy gives off the exact issues you are having now.) and everything worked great, almost.
I got the tablet working by simply adding some config options to the /etc/X11/xorg.conf file.
To get the tablet working add this to /etc/X11/xorg.conf:
Code:
Section "InputDevice"
Driver "wacom"
Identifier "cursor"
Option "Device" "/dev/ttyS1"
Option "Type" "cursor"
Option "ForceDevice" "ISDV4"
EndSection
Section "InputDevice"
Driver "wacom"
Identifier "stylus"
Option "Device" "/dev/ttyS1"
Option "Type" "stylus"
Option "ForceDevice" "ISDV4"
Option "Button2" "3"
EndSection
Section "InputDevice"
Driver "wacom"
Identifier "eraser"
Option "Device" "/dev/ttyS1"
Option "Type" "eraser"
Option "ForceDevice" "ISDV4"
EndSection
This also goes in the xorg.conf but inside the ServerLayout section:
Code:
InputDevice "cursor" "SendCoreEvents"
InputDevice "stylus" "SendCoreEvents"
InputDevice "eraser" "SendCoreEvents"
In Ubuntu Hoary the wireless worked. I just had to follow a howto to get WPA support for the intel 2200BG wireless card. The how to says to use the latest versions but that didn't work for me, I used the versions listed in the howto. Here's the howto for ubuntu with some luck it'll work on your distro too:

The sound worked but for some reason the "external amplifier" (don't know, don't care) was on. after fiddleing in the "volume control" found a switch to turn it off and laptop sound started to work.
No problem with ethernet. Haven't test the modem. The buttons don't work but I have no use for them so i have tried making them work. The usb ports are crap on the m275's! I had issues with them even in windows. Some times the work some times they don't but they work more reliably in linux.
The card reader seems to work off and on in linux, mostly off (haven't figured out why just yet.). works just fine in windows.
I tried mandriva 2005LE on this laptop and it blew up real bad...Then I tried Hoary and I stopped there. Tried breezy when it came out but it broke everything and fixed nothing (fresh install too). I was too lazy to tinker since hoary had worked so well and breezy offered nothing i considered worth the effort.
Yeah my post is mostly biased in favor of hoary but I hope this info is still of use to you no matter what distro you are using. Good luck! see ya.
