Modified Files:
	src/sys/dev/pci: machfb.c

Log Message:
disable mmap()ing the framebuffer at offset 0 on sparc64 because some ATI
firmware likes to put PCI memory resources into this range, notably a Rage
IIc which puts the 2nd register aperture to 0x2000.
This should allow a few graphics chips to work with XFree86 which previously
failed with something like this:
(WW) ATI:  PCI/AGP Mach64 in slot 2:5:0 could not be detected!
No devices to configure.  Configuration failed.

Thanks to Florian Stoehr for doing most of the work tracking this down.
