"RHIDE uses advanced VESA functions to save and restore the screen contents
and mode-specific settings, and some SVGAs and video drivers don't implement
these functions very well."

That makes me wonder if your ATI Radeon VE card is old enough that it lacks
VESA video modes.  But, that shouldn't be the case:

  "Register compatible with VGA "
  "BIOS compatible with VESA for super VGA "

and supports:
640x480,800x600,1027x768,1152x864,1280x1024,1600x1200,1920x1080,1920x1200,19
20x1440,2048x1536 in 256,64k,256k colors

If it was, you could've tried Scitech's UNIVBE drivers which adds VESA modes
for S/VGA only cards.  If the VESA is broken, they still might work if the
card is register compatible with one of the older video chipsets, such as
the S3 Trio.  On the other hand, if someone could post what video modes
RHIDE attempts to use, you might be able to test the modes on your card with
WHATVGA, part of the VGADOC package, to see if the card has a problem or if
it's missing some mode.
