OK.
In general, I'm using a number of comparable configuration both @home
and @work.
Home: Tyan Thunder K8WE, 2x270, Adaptec 29160.
Work: (couple of) HP wx9300, 2x275, LSI 320.
This alone should suggest a problem with the aic79xx driver and not the
kernel itself.
AFAICS by looking at the kernel change logs, 2.6.15/16 brought many
changes to this driver.

I'd suggest you do the following:
Boot from rescue CD, -enable- networking, let it detect the Fedora disk.
Chroot into it.
Now, "yum update" to the latest kernel. Try booting.

If it doesn't work:
Boot again from the rescue CD, follow the procedure.
-However-, this time enabled the update-testing repo in /etc/yum.repo.d.
There's a new 2.6.16 kernel in -testing... hopefully it'll work.

BTW, did FC4 work?
