wsmouse problem after APM resume

[Mike Lockwood <lockwood@pixo.com>]

Hi all,

I am running an OpenBSD current snapshot from April 19 on a Dell
Inspiron 3700 laptop.  Everything is working great, except I sometimes
have a problem with my mouse after resuming from sleep.  After resuming,
mouse will jump around randomly in the upper right hand corner of the
screen and post mouse down events, even though I didn't click the mouse.

I have had similar problems with XFree86 4.0.3 on this same laptop when
running Linux.  But on Linux I was able to work around the problem by
switching to a text console and then switching back to X. 
Unfortunately, this does not help on OpenBSD - the problem persists even
after killing and restarting the X server.  Since restarting X does not
clear up the problem, my suspicion is that the problem is in the wsmouse
or wscons support in the kernel.

Has anyone seen this or can anyone offer a suggestion on how to fix it? 
Is there a way to force the wsmouse driver to reinitialize itself when
this problem occurs?

I am using an external MS Intellimouse compatible mouse connected to the
PS/2 port.  Following is my dmesg from a GENERIC kernel.

TIA,
Mike
