Hmm, you're right that it's interesting that the resolution is being
detected differently by each of the three drivers, and the inconsistency
may indeed point to some sort of issue with -ati; I'll upstream it to
them for that reason.
However, from your description it seems that none of the drivers get it
quite perfect. I note that both -ati and -fglrx are seeing the physical
screen size as 0x0 mm, which suggests bad EDID; yet -radeonhd is getting
valid looking measurements. But you say that radeonhd is getting the
wrong refresh rate, which suggests that even it isn't quite perfect.
My guess is that your monitor provides EDID that is just slightly out of
wack from what the xserver expects, and it's mis-parsing it. Perhaps
each of the drivers has some correction code that handles the error
condition in a slightly different way, thus causing the range of
different results.
