Is this XF4.0.1 in `fbdev' mode? If yes, it's a bug in the X server. Setting
the DSP registers is part of the video mode initialization and thus is the
sole responsability of the frame buffer device, when running in `fbdev' mode.

Yes.  The server shows the SAME behavior using the fbdev driver and
the ati driver.  Also, as a note, the 3.3.6 XF68FB_Dev server with ati
accel also does the same thing!   So there's some code that's getting
used by all three that is wrong?

Both the fbdev and ati driver use the fbdvhw functions to do mode init and
the like. So it seems the bug is in the kernel driver (sorry Geert).

I don't see how it can be in the kernel driver, if running 3.3.6 XF68FB_Dev
changes the contents of the DSP registers.
