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.

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.
