It's amazing what happens when you actually read the documentation. 
lsmod was the clue.  I didn't see any scsi modules installed, which I 
thought was kinda wierd.  I grepped around the kernel documentation and 
came up with these:
scsi.txt
scsi-generic.txt

I discovered I was missing "sg", "ide-scsi" and "sr_mod"

I then read the man pages for lsmod, insmod and modprobe.

A quick edit to /etc/modules, and BAM! I'm back in business.

Thanks,
