Result!!! :-)

That fixes the problem with X for me on a kernel/world CVSupped ~ 11th May,
which rebuilding XFree86 failed to do. Previously, starting the X server might
or might not lock the machine for network access, but definately stopped the
console working (beep when try to switch VTs), and the server would eat 75%
of CPU.

Even just starting the server and moving the cursor around would lock up
after a little while, any other clients just seemed to hasten that..

Been up for about 20 minutes now, everything seems normal again. Thanks!

As an aside, that (previous) kernel gave me a "de0: autosense failed - cable
problem?" message everytime on bootup, (Cogent EM110 card) and the
ifconfig line with "media 100baseTX mediaopt full-duplex" in rc.conf didn't
help. (the link and RX lights were solid on the switch, no 100TX light despite
a message saying it had done the configuration, and no packets passed over
that interface at all).

I found that I had to take de0 down, delay a few seconds (?? 5 worked) and bring
it back up again.

Since applying that change to pmap.c, the Cogent Just Works again, which is
a very pleasant bonus :-)
