freebsd stable - Aug 2008 - lost scroll wheel of Intellimouse Explorer 4.0 on 7.0-STABLE

Hello,

Today I updated my desktop PC from FreeBSD 7.0R to 7-STABLE.  After
that, the scroll wheel of my Intellimouse Explorer 4.0 (USB wired)
stopped working.

I searched relevant information and found kern/123224 "[ums] Scroll
wheel breakage w/ USB MS Wireless Intellimouse Explorer 2.0".  The
symptom is quite similar.

ums0: <Microsoft Microsoft IntelliMouse Explorer, class 0/0, rev 2.00/4.24,
addr 2> on uhub0
ums0: 5 buttons and a TILT dir.

Note that there is no "Z dir" detected.

No one care about that?  It is hard for me to live without the mouse
wheel nowadays....

I tried another mouse and Z dir was detected properly, so it might be
specific to Microsoft products.

ums0: <Logitech USB-PS/2 Optical Mouse, class 0/0, rev 2.00/11.00, addr 2>
on uhub0
ums0: 3 buttons and Z dir.
