VIA C3 (Samuel 2/Ezra, 600 - 1000 MHz?, common on VIA EPIA-*: home
theatres etc) can't CMOV.

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.
