nvidia BIOSes call into chunks of system BIOS code that aren't available
after boot. They rewrite themselves so the c000:0003 entry point just
returns in order to prevent you from executing random code. It's not an
emulation issue. The only way to fix this is to finish nouveau's
implementation of the nvidia bios table bytecode and execute the init
tables on resume.
