uhid recently broken

I've been tracking -CURRENT for a few weeks now, and I noticed that
sometime after RELENG_5 was branched that my Gravis USB joystick (which
uses uhid(4)) was no longer being detected at boot, or at all. 

FreeBSD 6.0-CURRENT #0: Thu Aug 19 15:48:13 EDT 2004
    root at prophecy.dyndns.org:/usr/obj/usr/src/sys/PROPHECY

This kernel doesn't detect uhid0.

FreeBSD 5.2-CURRENT #0: Sun Aug 15 20:18:31 EDT 2004
    root at prophecy.dyndns.org:/usr/obj/usr/src/sys/PROPHECY

This one does.

Here's the relevant lines from dmesg on the working kernel:

ohci1: <SiS 5571 USB controller> mem 0xcffff000-0xcfffffff irq 11 at
device 1.3 on pci0
usb1: OHCI version 1.0, legacy support
usb1: <SiS 5571 USB controller> on ohci1
usb1: USB revision 1.0
uhub1: SiS OHCI root hub, class 9/0, rev 1.00/1.00, addr 1
uhub1: 3 ports with 3 removable, self powered
uhid0: Gravis GamePad Pro USB, rev 1.00/2.00, addr 2, iclass 3/0

I'm fairly certain that it's not a problem with USB overall because my USB 
mouse functions as it always has. If I can provide any more information, I'd be 
delighted to do so. I've checked UPDATING and both sys/conf/NOTES and 
sys/i386/conf/NOTES and none of the above mention anything specifically about 
uhid. There's also been no uhid-specific commits for a while, and nothing to 
USB overall which seems to be the culprit. Am I missing something obvious?

I abhor a system designed for the "user", if that word is a coded
pejorative meaning "stupid and unsophisticated".  -- Ken Thompson
