The reference might be wrong. We've had two different ones.
I think Tim's correct. The board has two xtal's on it, one connected to
the XP10 and the other to the S3. The S3 clock is the 133 MHz, this has
never really changed (as far as I know). The XP10 clock has been either
125MHz or 156.25 MHz (5/4 * 125). (the XP10 clock gets fed into the S3,
and it's the S3 that generates the video timing).
I'd check very carefully (with a magnifying lens) what sort of xtal's
are on your board. I'd then check to see what are the numbers that the
build scripts think you have for these xtals. If you look in
rtl/include/registers.txt you will find three places where there are
different numbers for production and pre-production boards.
