I was taking my information from here (Jeff Garzik's driver status
update page):

	http://linux.yyz.us/sata/sata-status.html

The entries on the Promise controllers look more encouraging to me
than the VIA controller (which is "0000:00:0f.0 RAID bus controller:
VIA Technologies, Inc. VIA VT6420 SATA RAID Controller (rev 80)"); the
entry for VIA says:

	VIA
	Summary: No TCQ. Looks like a PATA controller, but with full SATA
	control including hotplug and PM.

	libata driver status: Beta.

The Promise drivers are all labeled "production", not "Beta".
