[ros-diffs] [fireball] 28448: - Allow pci read/writes during proving BAR's size operation

[James Tabor]

Hi!
Could this be related to 28448? I mean could it fix this? The buffer address
goes down from 8XXXXX to 3fffff (yes backwards, I watch it) and faults.
This fault was before 28448 and on real hardware. Display is normal and mouse
moves.
Thanks,
James
