Of course they're getting loaded. As I said: I can run mdadm to assemble the 
RAID and mount them. If they weren't getting loaded, mdadm would do bupkis.

I'd be surprised if mdadm, on it's own:

* Surveyed the attached IDE and SCSI hardware

* Mapped them to the supporting kernel module(s)

* Loaded the kernel module(s)

I'd be surprised if mdadm has all that logic built-in. More than likely it 
just sweeps all the existing device nodes, looking for RAID partitions it 
can assemble together.

Actually, I can run 'fdisk /dev/sdb' and 'fdisk /dev/sdc' before running 
mdadm, and read the partition table. Everything is loaded, kernel-wise.

Bug 508554 -- F11 anaconda is seeing the disks, but intentionally ignoring 
them, for some reason.
