I tracked down the relevant change, and apparently it was to adjust for
a change in the 17 July 2003 version of the HAL interface in
mgadrivers-3.0-src.tgz from Matrox, where the function HALSetDisplayStart
had a name change, to MGASetDisplayStart.

The mga driver could be modified to handle both cases at runtime.

That's fine -- thanks.

You're welcome.  Thanks for the feedback.

A regular 'xterm' should work, at least.  I haven't seen this type of
problem in my 4.5.0 test installs, but I did run into a different problem
a little while back (very slow application startup) that was resolved
by runing 'fc-cache' as root.
