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.

Commit 8116188fdef594 ("nouveau/acpi: hook up to the MXM method for mux switching.") broke the build on non-x86 architectures due to the new dependency on MXM and MXM being an x86 platform driver. It built previously since the vga switcheroo registration routines were zereod out on !X86. The code was built in but unused.
