I just spent the weekend dealing with this stuff so maybe my
experiences will be helpful...
In 2.1.5-release, the GENERIC config file has psm0 disabled; you need
to remove "disable" from the psm0 line in the config file and remake
the kernel to get it to work. The "disabled, not probed" message would
be symptomatic of this.
Theoretically, that should do it. Even after I did that, the PS2 mouse
port on my motherboard wouldn't show up. The mailing list archives
suggested that maybe there are some problems with the probe code in
the psm driver. I finally got it to work by commenting the probe code
entirely and just making it return true every time; this is obviously
not the most portable and/or desireable solution, but I only run
FreeBSD on this one machine. (Let's hear it for free source code,
ladies and gents...) The file you would want to look at is
/usr/src/sys/i386/isa/psm.c, I believe.
