6.0-RC1 & ASUS P4R800-V/Sis 180 RAID

[Jeff Doolittle]

I upgraded my second machine to 6.0-RC1 this afternoon and have lost my 
raid mirror configured on an SIS 180 Raid controller (as provided on the 
ASUS P4R800-V motherboard).

I've read the release notes and double checked UPDATING and I didn't see 
any removal of existing support (other than 80386).  The array simply 
isn't even being picked up anymore (no AR0 device). 

What have I missed?

This is true regardless of a GENERIC or custom kernel.

The following is a cut-n-paste of the dmesg from my last GENERIC kernel 
boot:
