I encountered that same problem booting 3.0_RC5 on a GX620. I rebuilt the 
release kernels with:

usb/ehcireg.h    version1.23 2005/11/20 18:36:20 augustss Exp

and hacked 
pci/ehci_pci.c  to include the ehci_get_ownership code from the 1.21 version

This fixes the problem and doesn't seem to break anything else. This needs to 
be pulled up before 3.0 is released. I'll send-pr it later today unless 
someone has already done it.
