Are you using the 'nv' driver provided with X, or are you using NVIDIA's
'nvidia' driver[0]? I haven't a NVIDIA card in my FreeBSD box, but my Linux
box with gf4 & tnt2 work flawlessly with NVIDIA's 'nvidia' driver. May be
worth a shot, but YMMV. Does require a kernel recompile if the listed option
wasn't compiled in. Perhaps I'll find a TNT2 card laying around to throw in
my FBSD box and give this a try.

I just tested with an S3 virge. It has the same problem.

However, its a process called 'Xfree86' which consumes the CPU (I was wrong
when 
i previously
said it was xdm.

If I configure X to just use the matrox card (or the virge) it locks the
console up,
and nothing is displayed on the matrox/virge.

Testing with the S3 virge, If in the bios I set the PCI graphics card to be 
init'd first, X will
start on the virge fine when its configured as the only display. If I set it
to 
use the Nvidia
card only, It hangs and locks the console with the 'XFree86' process using
all 
available CPU.
The same goes for if the AGP card is set to init first in the bios, the PCI 
Virge/Matrox wont
work at all.

with the bios set to init the PCI card first, when I try to fire up xdm with

dual head mode enabled,
I get the crosshatch from the S3 card, and nothing on the Nvidia card.

I get the impression that whats failing is the (int10?) initialisation of
the 
2nd display
that isnt initialised by the motherboard bios. This probably isnt a port
issue, 
but an Xfree86 4.3.0
issue. This is assuming that the problem isnt with the Nvidia card's driver.

(the only thing
that has remained constant.

Have you done any further investigation yet Paul?
