Your last point makes it clear that your board has NOT gone through the
PnP initialization when you boot into either Win95 or FreeBSD.

What you may not be aware of is the fact that many motherboards these days
initiate a HARDWARE reset when you press Ctl-Alt-Del on your keyboard!
My motherboard (AMI Titan II Pentium) apparently does this.

How can you tell?  When you press Ctl-Alt-Del, does your screen go completely
blank, then come up showing (briefly) a line or two from your video card,
and then go through a FULL power-up reset sequence, including a memory test?
If so, then you've probably got a hard reset all-the-time motherboard (if
you just go immediately to the power up sequence but it does NOT do a memory
test after Ctl-Alt-Del then you may not have this "feature").

If your motherboard does do this, then it appears that you are "stuck"
until if/when the OS (FreeBSD in this case) properly handles PnP
initialization...
