He did this in the partition table or in the BIOS or in the SB
firmware?  cfdisk should be able to figure this out.  If it doesn't,
something weird is going on.

I don't see why; it could be that sfdisk takes more risks than cfdisk
does.  cfdisk was written by Kevin Martin (I think), anyway, it was
one of the BOGUS guys.  BOGUS's PMS is the package manager that
RedHat's RPM is based on.  They are very interested in safety.  If
cfdisk doesn't like your disk, you should be worried.

Have you tried the Ctrl-Alt-plus or whatever combination it is that
switches video modes?

Yes.  The clocks are needed for SVGA modes because of the bank
switching that needs to be done.  "Be vewwy vewwy quwiet; we'we
hunting WABBIT!"  This is tricky stuff.  Note that there are two
clocks you need to worry about, the SVGA board's clocks (modern
XFree86 X servers (3.1+, Ithink) mostly do this automagically but you
may need to fiddle with it).  Or maybe there isn't a Tseng Server?
Yes, there is.  Check to make sure that /usr/X11R6/bin/X is symlinked
to XF86_W32.

The second clock is for the monitor.  If you don't tell the XF86Config
what horizontal and vertical syncs your monitor can handle, it will be 
conservative and assume that only the VGA is safe.  You might want to
post your /etc/XF86Config.
