Ok here's an update:
I've now tested putting the vram at the following locations (in order):
 - 0x00000000: This is the same location as vram used to be at before the
               identified bad commit and works.
 - 0x10000000: This is before GTT (which starts at 0xd0000000), with some
               room to spare. This works without freezing, tested for two days.
 - 0xf0000000: This is after GTT (which ends at 0xdfffffff), with some room to
               spare. This works, tested for two days.
 - 0xcc000000: This is directly in front of GTT, with no room to spare. This
               works, tested for several days.
 - 0xe0000000: This is directly behind GTT, with no room to spare. This where
               vram is placed starting with the identified commit, and as
               expected it froze within minutes.
