Excellent!  I had thought of this, but discounted it.  Maybe someone
can explain the following...

When I initially build XFree 4.0.0, I did not have the MVI patch in my
kernel.  After I applied the MVI patch, I rebuilt XFree and friends
from scratch.  Everything seemed to work just fine in both cases...

Hummm - before I applied the MVI patch, I was starting X from the
command line via "startx" rather than from xdm in inittab?

Thanks in advance,
Craig
