I looked into this. I don't know how it could ever have worked for
you in the past -- the crash is occurring because the kernel is
compiled with 3DNOW-specific instructions (in particular a
3dnow-specific PREFETCH instruction) that Intel CPUs simply do not
support. The system therefore crashes with an entirely legitimate
"invalid opcode" fault.

If you really want a kernel that will work on both Cyrix/C3 and P3,
try selecting "Pentium-Pro" as processor type. If that fails I can
look at allowing configuration of "Pentium Classic".
