Modified:
programs/Xserver/hw/xfree86/drivers/ati/radeon_mergedfb.c Back out
RadeonWaitForIdleMMIO that I put in earlier.
From discussion on dri-devel we do not need to be as careful with INREG()
access on Radeons as we are on mach64 chips.
The fix is backed out due to:
it breaks DRI on SMP systems (due to absense of the lock in mouse handling
functions)
I am no longer able to reproduce the lockup I saw before
