I have the same hardware (0x24cd8086) on a Dell-branded board with the same 
results.  I think so far only the NEC-based EHCI controllers are verified to 
work -- I don't know of anyone who has had success with the Intel ones.

It doesn't.  It makes the probe message prettier but I get the same problem 
(unrecoverable error).  If you have time, could you try compiling with 
"options USB_DEBUG" and setting the sysctl hw.usb.debug=3 and 
hw.usb.ehci.debug=6 ?  Be warned that that will generate a LOT of debug 
output.
