Hi, ... I am seing this also, sortof, when i VT switch away from X, and then skill or stop X in some way, the radeonfb text console is corrupted. When i restart X blindly, then the console is ok again. When i kill X from inside X, then there is no problem.
I may have misunderstood the dontswitchvt option, but i feel that forbidding VT switching is no real option here, but then the option probably does something more subtle :). Anyway, i am at your disposition if you need this bug investigated, and may look into this myself also as time permits. Friendly, Sven Luther
