Ok so based on previous suggestions I did a mkinitrd:

mkinitrd -f --preload=ide-disk --preload=ide-generic

Upon looking further in the /lib/modules of the xen kernel I'm not seeing any
other potential candidates to try preloading. When I made the initrd without
the preload parameters, my drives weren't found. Does anyone have any
suggestions on what I should put into the initrd or specify explicitly in
order to have my drives recognized properly?

This is the driver:
NFORCE2: IDE controller at PCI slot 0000:00:09.0

Run "kmodule"?
"cat /etc/modprobe.conf" might hint at something also.
