[CentOS] Unable to boot xen dom0 on IBM System x3250

I have an IBM System x 3250 that successfully boots using the standard
kernel (2.6.18-8.1.10.el5) but fails to boot with the xen kernel. The kernel
appears to fail when it attempts to initialize the driver for the onboard
SAS controller (LSI Logic / Symbios Logic SAS1064E PCI-Express Fusion-MPT
SAS). Can anyone provide any advice? Here's the relevant info. Please let me
know if any other information would be helpful.

IBM System x 3250: dual-core Pentium D 3GHz, 3GB memory
