[Qemu-devel] [PATCH 2/6] vga: increase priority of 0xa0000 memory region

["Hervé Poussineau" <hpoussin@reactos.org>]

VGA device registers vram as BAR 0. If this BAR is activated as a very low address which
crosses 0xa0000-0xbffff, low memory region is not accessible anymore.

This fixes display on PReP machine if we enable PCI mapping at address 0.
