I have a 9650SE-8LP on the current Centos 5.1 x86_64 Xen kernel
operating with no problems.  Admittedly it isn't very busy at the
moment, but it is detected no problem.

The Centos kernel is 2.6.18-53.1.14.el5xen.

Dmesg output:

3ware 9000 Storage Controller device driver for Linux v2.26.02.008.
ACPI: PCI Interrupt 0000:0b:00.0[A] -> GSI 16 (level, low) -> IRQ 16

3w-9xxx: scsi0: Found a 3ware 9000 Storage Controller at 0xbab00000,
