Default Re: Complete hang in 285.03 when changing brightness on NVS 4200M

I found that passing pci=noacpi as a boot parameter works around this issue for me. However it seems I cannot control brightness under X.

This might be a kernel bug and not an nvidia driver bug, because I later found that I could reproduce this from a virtual console without X running or the nvidia kernel module loaded.
