USB causing slow boot

[myob]

I've an nVidia MPC73 chipset, and having seriously slow boot problems. It was apparent before alpha1, currently using hrev33886 gcc2.

I've tracked it down via the on-screen boot log to be down to the usb/usb_disk drivers. the offending section of syslog is below:

KERN: ahci: ahci_supports_device
KERN: usb uhci: no devices found
KERN: usb ohci -1: iospace offset: 0xe6106000

I've got a multi-type card reader on the front that I think this is referring to - it usually presents as four devices though.

Right, that messed up the syslog entirely. Attached.
