"shining" on irc reported an issue after reloading the nouveau module.

Oct 21 21:09:07 xps-m1530 kernel: [38358.282213] vmap allocation for size
33558528 failed: use vmalloc=<size> to increase size.

Failed to init RAMIN mapping, limited instance memory available

It appears we are not gracefully handling the lack of ramin mapping. Is it
viable to move around the 1MB mapping in the mmio bar or maybe we should fail
altogether.

I haven't looked into it deeply, just want to avoid loosing the information.
