As a past contributor and somebody who does this professionally, I
understand the risks and am happily walking on the hot coals of my own
volition. Thanks for the tip, though :-)

I didn't know this as I've never had any experience with GNOME. That is one
nasty little bug, though. Those files can be quite the pain to get rid of.

I think 2.2.10's driver is just the 2.3.6 driver code. It may be working
for you out of sheer luck or perhaps the fix was enough for Rage II+. The
problem persists on my Rage Pro.

Well, as far as I can tell the 2.3.6 fb code only partially solves the
problem. We probe for the MCLK now but perhaps we should also probe for PLL
clock (are we already?). Can't we just get these values from OF? I thought
I saw an entry in the card's device tree for such stuff.
