With Redhat 7.1 and original kernel Basilisk runs.
With Redhat 7.2 and kernel 2.4.9-13, Basilisk crashes 
with:
Xlib: unexpected async reply (sequence 0x2d)!
Gdk-ERROR **: BadRequest (invalid request code or no 
such operation)

Looks like an X/Video driver problem rather than a Basilisk
problem, since it works with the earlier kernel version,
see if its fixed in latest X/Kernel. What Video card/driver
is it, have you got a different one?!

Similarly for original 2.4.7 kernel of RH7.2. In addition
this Basilisk (0.9.x) fails on athlon, PIII, and PIV. The
JIT compiler nearly works but dies at the last minute.
However, Basilisk 0.8 from a year or so ago does work,
albeit more slowly.
