PS/2 port problem

I just discovered that this is a very old problem, but I just noticed
it today.  On boot I see this:

psm0: failed to get data.
psm0: <PS/2 Mouse> irq 12 on atkbdc0
psm0: model Generic PS/2 mouse, device ID 0

The mouse works in spite of that error message, but only the first
time the psm0 device is used.  Until today I was using moused to
manage the mouse, so psm0 was only opened at boot, and worked
correctly because I never shut down moused until reboot.

Now I find that if I stop moused and try to start it again, I see
'cannot open /dev/psm0, device not configured' and the only thing
I can do is reboot the machine.  X acts the same way even if I don't
use moused.

This is specific to DragonFly (FreeBSD-current and linux both work
correctly on the same machine) and the problem goes back at least
as far as DF 1.5 (which I also still have on this same machine).

Anyone else seeing this?  Any ideas for debugging?
