I had a similar issue with an Asus M3N-HT series board with Nvidia 780a
chipset.  I was able to boot and install CentOS 5.2 x86_64 using passing
kernel option pci=nomsi even though I was never able to get the CentOS
live cd to boot.  lspci could not id the chip set either.  I was able to
boot several ubuntu live cd's to determine nic and audio driver.  I
doubt you will have a satisfactory driver for nic or audio with present
centos kernel.  Also tried rhel 5.3 beta kernel which appeared to work
without issue except still no support for nic or audio.  Finally
compiled vanilla kernel 2.6.26.8 from kernel.org and everything works.

The point of all this rambling is that you may have to compile a custom
kernel to make everything work or go to a more bleeding edge
distribution.

Google mcp78b tells me many are getting errors with 2.6.26. on that
chipset.  IIRC ubuntu 8.10 uses 2.6.27 kernel and might be the way to
go.

Good luck.
