[ale] Motherboard Drives First, Please!

[Jeff Hubbs]

Supermicro X7DBE+ mobo, two 3ware SAS RAID controllers and one 3ware 
SATA raid controller, four SATA drives on the mobo. How to make sda-sdd 
always be the mobo drives? I'm going to test JBODding the controllers 
and I want the four drives that work the OS to always appear as sda-sdd.

I've already tried disabling bootable flags on the controllers and 
fooling around with the boot order in the mobo BIOS but it's not 
working.  FWIW, the Gentoo LiveCD puts sda on the mobo's SATA0 like I'd 
expect.
