This issue has been fixed in 2.4.20-pre1. I don't know exactly what
patch fixed it, but I suspect it could be Alan's massive patch.

o fix aic7xxx build when PCI=n

It's really hard for me to tell where it was fixed, all I know is it
working now!

So if you had the problem attached to this email, it looks like it's
sovled in 2.4.20pre1. Or you can revert to 2.4.18.

Hope this helps someone.
