If anyone has any objections, please let me know. =============== commit a3d0b1218d351c6e6f3cea36abe22236a08cb246 upstream. There appear to be a crop of new hardware where the vbios is not available from PROM/PRAMIN, but there is a valid _ROM method in ACPI. The data read from PCIROM almost invariably contains invalid instructions (still has the x86 opcodes), which makes this a low-risk way to try to obtain a valid vbios image.
