That should not be an issue. However in the BIOS one does need to set the 
console redirection parameters if you want a console interface over the 
serial port.

Two things to look at:
1) Some better RAM.
2) More current Tyan 466N-4M BIOS.
Early revs as shipped with boards are "limited"
Tyan already has at least version 2466N-4M "Q" on their ftp, and "T" or 
higher will be there soon, I am sure..
