I (PR 40056 submitter) tested your patch with my

  ATI Technologies SB700/SB800 USB EHCI Controller (rev. 0x00)

with my amd64 kernel. Patch itself applied flawlessly, but after the
new kernel amdehci didn't match in my case. Sprinkling some printf's
showed that (in amdehci_sb700_match)

  PCI_REVISION(pa->pa_id) == 0x02

for my mainboard (under amd64).

Extending the switch-case's of that function with this value (0x02)
made the kernel panicing during further usb processing (though amdehci
matches now I guess ;-)).

So, there's is something different in my case...

Any information I can provide / you need for further analysis?
