Updating the MSI Wind to 10.5.6 has given me some graphics problems. Yes I got stuck at 800 x 600. All the previous tricks failed. Fianlly after much searching I found a post at msiwind.net which pointed me to some new drivers. Using kexthelper I installed, rebooted and crossed my fingers.
Small thing is lack of Quartz Extreme though. Lets see if I can fix that.
