Have the same problems since karmic, but only when system started with an external monitor plugged in. I noticed that downgrading kernel then fixed that issue (but brought up many new ones).Now I was trying to install Lucid, and since gnome loaded I had white flickering and kind of "drunken-view-mode", which made the system barely usable. Switching off KMS made the miracle! Installing now.
BTW... what negative consequences can disabling KMS have other than losing plymouth boot screen?
