I wanted to relay the following here in the bug report...I was notified
of a commit in the latest upstream v3.5.3 release. I thought it would
be interesting to test the latest Ubuntu 3.5.0-13.13 which was rebased
to this latest v3.5.3 upstream stable release. Narinder and I didn't
originally test this latest Ubuntu kernel as I only uploaded it
yesterday. Anyways, I see the following commit included there:

drm/mgag200: fix G200ER pll picking algorithm
commit 9830605d4c070b16ec5c24a75503877cc7698409 upstream.
The original code was misported from the X driver,
a) an int went to unsigned int, breaking the downward counting testm code
b) the port did the vco/computed clock bits completely wrong.
This fixes an infinite loop on modprobe on some Dell servers with the G200ER
chipset variant.
Found in internal testing.

So the issue which was being seen might be the fix with the above and
thus allow us to keep the mgag200 driver enabled. I figured it wouldn't
hurt to test anyways. Thanks.
