BTW, according to Daniël Mantione the DSP calculations in atyfb have always
been wrong (but apparently worked on most machines due to sheer luck ;-), so
you may want to compare with aty_dsp_gt() in current 2.4.

Well, wrong in the sense that the calculations they make are very
different from both Ati's example code and XFree86 code. The original author
(unknown to me at this time) might have had reasons to code it like this,
but it looks realistic that he simply tried to modify it till it worked
for him.

I remember starting from ATI sample code, but that didn't work well, and
modifying that based on info from the XFree86 code, until it worked.
