The M-Audio Quattro USB still locks up the machine though. I'm sure it's due to one of the three or four USB patches applied to ALSA, but I can't get the kernel to compile without them, so I don't know how to fix it. It locks up before anything gets written to /var/log/messages.
Hotplug still tries to use OSS for USB audio and midi though. Adding 'audio' and 'usb-midi' to /etc/hotplug/blacklist fixes the problem.
