Asus M2N SLI Deluxe

[fred]

Trying to boot an Asus M2N SLI Deluxe motherboard. It is not listed in 
the supported motherboard list, but I found this thread: 
http://www.coreboot.org/pipermail/coreboot/2007-October/026410.html, but 
with no clear resolution. If testing is needed, I have the
motherboard with the original BIOS backed up and a new one ready to go. 
Thanks.
