I also used to restart moused in rc.resume, until this clue from jkim@

psm(4):
bit 13 HOOKRESUME
The built-in PS/2 pointing device of some laptop computers is
somehow not operable immediately after the system `resumes' from
the power saving mode, though it will eventually become available.
There are reports that stimulating the device by performing I/O
will help waking up the device quickly. This flag will enable a
piece of code in the psm driver to hook the `resume' event and
exercise some harmless I/O operations on the device.
bit 14 INITAFTERSUSPEND
This flag adds more drastic action for the above problem. It will
cause the psm driver to reset and re-initialize the pointing
device after the `resume' event. It has no effect unless the
HOOKRESUME flag is set as well.
I always use hint.psm.0.flags="0x6000" in /boot/loader.conf, i.e.,
turn on both HOOKRESUME and INITAFTERSUSPEND, to work around similar
problem on different laptop.
=======
This works reliably for me on my Thinkpad:
# 29/9/10 thanks Jung-uk Kim .. so can remove moused restart from rc.resume
hint.psm.0.flags="0x6000"
It's psm of course so I doubt it could help with ums(4), which appears
to be a hint-free zone, but it should work for you, Garrett.
cheers, Ian
