AFAIK they fixed that in newer BIOS with a microcode update. It's slow, but it works.
Our firewall here uses a Via C3-600 CPU, and CMOV has never worked on it.
But based upon your posting, I have today upgraded the BIOS to the
latest (2004) version.
Now.. how can I check whether CMOV works or not? It's not listed in /proc/cpuinfo.

Compile just about any C program with -march=i686.
