Well, squake is linked against libc5.  AFAIK, id isn't going to
recompile it to link against glibc. :/  However, the SVGALib I have
(stock RH 5.1) is linked against glibc, and quake was working, so I
don't think this should be a problem.

Not really, it's screws the screen up until I CTL-C from quake, or,
using my memory of the keyboard commands select "Quit" and "Yes, I'm a
Wuss". ;)

I'll try that and see.

Well, I was trying to avoid rebooting to get back to the VGA console.  
I haven't seen anything that allows you to dynamically switch between
VGA console and fbcon.  libggi was suggested as a way to use SVGALib
programs (e.g., Quake) on an fbcon, by providing a wrapper for the
svgalib.  And I really dislike rebooting, especially my Linux box. ;)
