In an older post I wrote about supporting the new e1000 in CentOS 5.

Apparently on machines with the same new Intel board, not only the Ethernet driver  (e1000) should be updated but also the sound driver (snd-hda-intel) and graphics driver (xorg i810 driver).

Lots of work, eh? Well - no! CentOS / RHEL 5.1 just contain them all.

I didn't test the 3D graphics driver though.
