I don't think that's a side-effect. If you look at /var/log/Xorg.0.log
it should show the modes that it's trying to use. From what I've seen, X
isn't able to query the monitor properly. This may be another ppc signed
char bug embedded deep within.
Net result is that you have to specify the monitor's HorizSync and
VertRefresh ranges so Xorg can pick an appropriate modeline. It'll take
me a while to dig up my mini's Xorg.conf - Tilman, if you're reading, do
you have your's handy ?

I think you have to keep the non ifdef'd lines of the form
vgaHWSave(pScrn, &hwp->SavedReg, VGA_SR_ALL);
... since that was the issue when VTY switching.
later,
Peter.
