I is a linux lappeh...at least for the time being!
Am running Mandriva Linux on the Q45; off the live cd at the moment.
I can report that the boot is reasonably painless, although I had to put it in acpi=off mode. It detected the Intel wireless LAN card without difficulty and played nicely with my Linksys box.

And I could get used to working in three windows at once...perhaps.
Update: Installed, and it works! Not only that, but I can see my Windows drive from in here and get stuff out of it. Have already installed the NTFS plugin. The install went OK, too; reasonably quick and unsporky. Better yet, I've added the shebang lines to various python thingies and they all run blisteringly fast.
