These two patches get radeon KMS working on the Sun XVR-300, a FireMV 2200 PCIe (RV370) board, in sparc64 hosts.
Patch 1 fixes an Oops that any posted radeon card on sparc64 hits in igp_read_bios_from_vram(), which dereferences an ioremap() cookie to check the VBIOS signature. It is tagged for stable. Patch 2 adds a legacy connector table for the XVR-300, which has no COMBIOS for the driver to parse, so both DVI-I outputs are found. The XVR-300 needs both. Tested on a Sun Ultra 45 with an XVR-300.
