I'm running LinuxMint 4.0 on IBM Thinkpad R60. everything works ok. graphic card (intel) supported.
Compiz running well with all the bell and whistle.
function keys mostly work except the lcd/projector F7. You need to modify the xconfig
to make 2nd monitor (projector) work. Plenty of ubuntu site explain about this.

I've run older Mint (2.0-3.0) and Opensuse 10.1-10.2 all running ok.
