usb 2.0 dell inspirion 8500

[quel at quelrod.net]

I recently got a usb 2.0 hard drive to which I painfully wait for 1MB/s 
transfers.  According to dmesg fbsd is only doing 1.0:
usb0: <Intel 82801DB (ICH4) USB controller USB-A> on uhci0
usb0: USB revision 1.0
usb1: <Intel 82801DB (ICH4) USB controller USB-B> on uhci1
usb1: USB revision 1.0
usb2: <Intel 82801DB (ICH4) USB controller USB-C> on uhci2
usb2: USB revision 1.0

(Yes i double checked my laptop does indeed have usb 2.0)

I saw that ehci had usb 2.0 support comitted.  Is this coming for uhci?  I 
suppose it's too late to get this into 5.2 -RELEASE.
