Ah, this is a FAQ that has bitten quite a few people (myself included).  In 
-current, there are two NOTES files, one in sys/conf for machine-independent 
options, and one in sys/i386/conf for i386-specific options.  Almost all of 
the USB-related options are in the former.

Actually, I think it may not work after all.  I finally got my hands on that 
board that uses a similar controller, and it gets detected just fine as the 
Intel controller with the patch, or simply as a generic EHCI without it.  
However, when I plug in a USB 2.0 device (1.x devices attach to the UHCI 
instead), it promptly spits out "ehci0: unrecoverable error, controller 
halted".  Then it disables the port and the device of course doesn't work :-(

I've been meaning to set aside some time to try to get some more useful 
debugging information, but haven't gotten a good opportunity to do it yet.
