Sorry, I guess I'm not very clear sometimes. I boot linux from BootX without
any kernel arguments (other than root device), and with No Video Driver
unchecked. The kernel will then proceed to use as console that video card
and that monitor which the macos were using as its primary display (where the
menubar was). The monitor is initialized to the same resolution macos had it
in. The other monitor is not touched, although the kernel knows it's there:
0 (13:31)(root@peidran)(~)# dmesg | grep fb
aty128fb: detected XCLK=0x2aae, ref_div=0x36
aty128fb: Rage128 RE (PCI) [chip rev 0x2] 16M 128-bit SDR SGRAM (1:1)
fb0: ATY Rage128 frame buffer device on /bandit/ATY,Rage128v

No, since I wasn't specifying one for the first. I used to do that, but it
didn't seem to make much difference, so I stopped using it. I have the modes
that I like for each monitor stored in /etc/fb.modes in case the kernel or X
messes something up.

Perhaps there's some way of not letting X know when I've switched away from
it? All I want to happen when I switch from one framebuffer to the other is
for my mouse and keyboard input to go to whatever is resident on that
framebuffer.
Thanks again,
