Have you tried flashing the board to the most recent BIOS?  I know, e.g., 
that the Fedora preview release had issues with the Tyan boards unless 
they were completely up to date regarding the BIOS.

FWIW, I'm running RHEL3 on an 8GB RAM, dual Opteron box with the Rioworks 
HDAMA motherboard with no such odd messages in the logs.
