I wish I could copy/paste the output of the kernel messages here but I
am too lazy to write them all down on paper and then type them in here.
It doesn't seem that the Xen kernel sees the disks at all. The software
raid drivers seem to be loading (I see the md RAID 0, RAID 1, RAID 5,
etc stuff load) but there is never any mention of any /dev/sdx
or /dev/mdx in the kernel messages.

Is there any way to force load the aic79xx driver to load on the grub
command line?

Unfortunately this made no difference :(

This Dell machine is giving me a little bit too much grief for nothing -
Urge to kill rising ...
