Macbook Pro 7,1 (with 320M) with EFI boot: Failed to initialize display subsystem
This is a standard 64-bit ArchLinux install on the mid 2010 13" MacBook Pro model using EFI boot (no BIOS emulation). Graphics driver is NVIDIA 295.20.
Upon starting, the X server fails with "(EE) NVIDIA(0): Failed to initialize the display subsystem for the NVIDIA" (see attachment), resulting in permanent loss of the screen, independent of whether xorg.conf is empty or generated by the nvidia-xconfig.
Note that legacy booting (using the BIOS emulation of the Apple firmware) works well (but has other, non-relevant issues). Dumping the video bios and adding "loadbios vbios.bin int10.bin" to the EFI Grub2 configuration didn't change much.
