I use a Soekris Net5501 (amd Geode and cs5536 chip) too since
FreeBSD 6.X and I did not notice any problem with an usb disk (myne is
a 160 go disk). It is my home "all-in-one box" doing backup and NAS
(some times I make a backup on a usb drive)

I follow the Soekris mailing list and I do not remembered anymone
complaining about usb disk problems too.
