A while back I had to debug a VC hanging problem with the S3 Savage4
card. I'm slightly familiar with what goes on when the VC is
switched.
I don't see how FVWM can be to blame. FVWM might be doing something
thats triggering the problem, like using a memory location on the
card or a feature that the Xterm or some other window manager
might not be using, but I think the problem is in the VC logic.
It was in my case.
If you can log into the machine while its hung, and attach dbx
to the xserver, that might point to the problem. It would have
in my case, except that I couldn't log in from anywhere else,
and had to debug the problem with lots of printfs and flushes.
