[Maverick] [PATCH 0/4] KMS Disablement for i8xx

[Steven]

Dear Kernel Team,

Please do NOT reapply these patches. UMS causes the majority of 8xx cards to
boot to a black screen on Lucid and forward. I spent at least a month fixing
probably a hundred different peoples' install problems after Lucid was
released because of these patches.

If you do decide to reapply these, PLEASE consider paying especially close
attention to bugs related to this change, at the very least.

I realize support on i8xx is difficult, but please be aware that these
patches caused more harm than good for the Lucid release. Thank you for your
time.

-Stenten
