"startx -- -probeonly" also crashes linux when the ati drivers are
selected.

Here's the log, which ends somewhat abruptly.

That's quite little VRAM :)

Yep, that can't really be the 2048 bug anymore.

But that's also quite a lot of mach64 cards. Are there really two GI's in
the machine?

No PCI regions overlap so my patch doesn't apply.

Do you have an atyfb for each head? If so, try also passing the "fbdev" option
with the devices for the ati driver.

You will have to pass multipe atyfb= kernel parameters to make the kernel
initialize one framebuffer device for each. Right now I doubt
atyfb_of_init will do the right thing here - could you post the kernel
boot messages again? I wonder if the device you specify via the busid is
the same the kernel initialized as atyfb.

Also helpful: a dump of the OF device tree.
