Good to hear, Josh.

Perhaps behind a '#' like some other example solutions in rc.resume?

If mouse uses a PS/2 interface (including many/most? builtin pads and 
pointers) then I found the advice given below works well, after having 
also used 'moused restart' in rc.resume for some years previously, on 
both an old Compaq Armada and on my Thinkpad T23.

If the mouse is connected to PS/2 port, the following device flags may
help.

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.
