[PATCH] drm/nouveau: fix early vram corruption originating from vgacon
...AGE_SYSTEM_ONLY / PAGE_NOT_PRESENT"
which eventually lead to complete hang.
Disabling access to VGA memory (through 0x54 PCI config space register) is
enough to fix it, but it breaks copying screen data between old and new
console (because old data is inaccessible). But blanking console (with
entering_gfx==1) is enough to move vgacon screen buffer from VRAM to RAM
and let handover to work correctly.
