I'm using Radeon 9200SE in a dual-head configuration and had a hard
hang problem when trying to exit the Xserver or to switch to a text
console VT.  (I don't remember exactly, it's a long ago.)

Here is a workaround for the problem.  As committing this patch may
cause negative effect for single-headed use, I'm just posting this
patch here for reference & record.
