Well, when you're looking for a graphics card, it seemed sensible to read
all the reviews I could find about it. Including the ones on the
overclocking style websites...

Errruhm...
I think the ati driver reads the current setting, and outputs it along
with the rest of the startup stuff. One may be able to tweak the source
to, set a new value, but I'm not terribly sure how well that would work. I
know that some (older, Millenium, Millenium 2, and Mystique) Matrox cards
have funny things about their clock and can break if you try overclocking
them in the 'wrong' way.
Anyway, check to see if you have the line:
(II) RADEON(0): PLL parameters: rf=2700 rd=60 min=12000 max=35000; xclk=18300
in your log. min and max should be the same, xclk is, I believe, the
interesting one (but I only have the one board, so it may be a completely
different occourance of the number 183...).
Then, there is the possibility that under-clocking your FSB, and hence AGP
port would also slow it down, but that's not exactly gonna help isolate
the problem...
Other than that, there is the windoze powerstrip program, which you could
try running with wine. As root. With a little luck it might possibly just
work. Maybe.
