I tested with FreeSBIE 2.0 beta, based on FreeBSD 6.1-RELEASE-p3 and I
didn't see the problem.  Given that I tried kernels back to March 1st,
I went to expect my kernel config file was the culprit.
Thus I've just tried a GENERIC kernel from the latest -CURRENT and
the problem went away:

% psm0: unable to allocate IRQ
% psmcpnp0: <PS/2 mouse port> irq 12 on acpi0
% psm0: current command byte:0047
% psm0: strange result for test aux port (1).
% psm0: <PS/2 Mouse> irq 12 on atkbdc0
% psm0: [GIANT-LOCKED]
% psm0: model Generic PS/2 mouse, device ID 0-00, 2 buttons
% psm0: config:00000000, flags:00000008, packet size:3
% psm0: syncmask:c0, syncbits:00

I tried to add/remove kbdmux and apic, but this resulted in nothing
better.
My configuration file is attached, I would be glad if someone pointed
out what makes my psm(4) fail.

Thank you.
