I have a Toshiba Tecra M1 with the Trident CyberBlade XP4m32 and fixed the problem by getting an updated Trident driver from the latest unstable Debian release. The new .so file for Trident fixed all of my issues with incorrect scrolling, desktop disappearing, etc. I had 6.10 installed with all updates possible to 3/5/07 installed.
