There is a problem discovered in recent versions of ATI Mach64 driver in X.org on sparc64 architecture. In short, the driver fails to mmap MMIO aperture (PCI resource #2). I've found that kernel's __pci_mmap_make_offset() returns EINVAL. It checks whether user attempts to mmap more than the resource length, which is 0x1000 bytes in our case. But PAGE_SIZE on SPARC64 is 0x2000 and this is what actually is being mmaped. So __pci_mmap_make_offset() failed for this PCI resource.
