I have XUbuntu 9.10 installed on a Toshiba NB200 netbook with Intel video card that's handled with i915 driver.
With 2.6.31 stable, recommended kernel everything but WiFi works fine: Atheros ath9k WiFi shows too small signal power and loses packets in 'bursts' sometimes.
With 2.6.32-* (I tested -9 to -11 from Ubuntu's kernel unstable ppa) everything works fine just prior to first suspend:
echo mem >/sys/power/state. After it random unidentified fullscreen 'one-frame' flickering begins in Xorg, and after a couple of minutes everything eventually hangs while showing filled grey (not white; it is like default button colour) screen; no X keys are working: Ctrl+Alt+Fn don't, blind typing in console too. Magic SysRq still works and I was able to reboot.
Also there is one out-of-tree kernel module called
omnibook that is required to turn on WiFi and Bluetooth.
