Try the new patch. Note that I posted a second one today, right after
the first one, that fixes a engine lockup bug (see my second mail).

The original patch had a bug where some of the CPU "HID" registers
weren't properly restored for 7447A type CPUs. If you had one of these,
it could explain the issue.
