Xen Boot Fails With Lsi Megaraid Sata 150-4

I'm testing the LSI MegaRAID SATA 150-4 on a server which will be running the Xen hypervisor. I've booted into the kernel but it doesn't seem like the megaraid_mbox module is being loaded. It gets to the point where it is looking for the boot partition (which is actually / found at /dev/sda1) but, it can't find it. It simply states "cannot find /dev/sda1". If I try a second time to find it I get dumped to /bin/sh because nothing was loaded.

How do I load the module into the Xen kernel at boot? Or do I have to recompile the kernel with the driver built in?

***I added the megaraid_mbox module to the appropriate sysconfig file and everything worked.
