Yeah, that's the message I was thinking of.

Hmm. You said earlier that you have an Asus K8V Deluxe SE. You are using
the onboard IDE, right? The driver above should do it, but it's possible
that since you have a very recent board the driver doesn't yet support
your IDE chipset. Unless I'm on the wrong track; I haven't had a VIA
motherboard in a long time.

Please send the output of:
$ lspci

and also:
$ lspci -n

and also the section of /var/log/messages from when you last booted.
