I've finally ended up using 2.5 on a box with OHCI. Its a little bit
wobbly to say the least

- Some boots it finds the root hub but nothing beyond it

- If you reload it then it does this

Oct 29 11:49:18 irongate kernel: drivers/usb/host/ohci-pci.c: 00:07.4: AMD756 erratum 
4 workaround
Oct 29 11:49:18 irongate kernel: drivers/usb/core/hcd.c: 
usb_register_root_hub_Rsmp_121543ac - usb_new_device failed with value -17
Oct 29 11:49:18 irongate kernel: drivers/usb/host/ohci-pci.c: can't start 00:07.4
Oct 29 11:49:18 irongate kernel: drivers/usb/core/hcd-pci.c: remove: 00:07.4, state 0
Oct 29 11:49:18 irongate kernel: drivers/usb/core/hcd.c: USB bus 1 deregistered

- Other times it does this

Oct 29 11:56:13 irongate kernel: drivers/usb/host/ohci-q.c: 00:07.4 bad entry  f6f6341

At which point touching the USB mouse results in an oops in ohci_irq 
called from usb_hcd_irq and dies with no useful looking info except that the eax
register holds the pattern A7A7A7A7

Anything you want testing ?
