-    vgaHWSave(pScrn, &hwp->SavedReg, VGA_SR_ALL); /* save mode, fonts, cmap */
+    if (info->VBIOS)
+        vgaHWSave(pScrn, &hwp->SavedReg, VGA_SR_ALL); /* save mode, fonts, cmap */
+    else
+        vgaHWSave(pScrn, &hwp->SavedReg, VGA_SR_MODE); /* save mode */


The above hunk of your patch doesn't make sense.  What does having a video
BIOS (or the lack of) have to do with being able to save VGA fonts and
color map?  That will break boards on many platforms.

A lowerlevel fix to vgaHW.c is probably better, but keep in mind this is
only for PowerMac's and not for all PPC machines.
