Did you look at SATA alone?
No. I don't think I have any pure-SATA machines. I suppose I could
disable the drivers for non-SATA and see what happens.
Since SATA does its own scan asynchronously from SCSI itself, doing this
seems

Here's an updated version. It shaves 5 seconds off boot time on my
configuration (qla2xxx, emulex, two ata_piix, dual fusion), but could
save more or less on other setups.
I think I can remove the 'sync'

As a tangent, I would prefer a more natural representation than
current, where there is a 1-1 correspondence
