Further data point, but currently inexplicable, a similar issue haunted
Fedora 12 on the same hardware, but not Windows 7, but now has
disappeared on either Linux system after rearranging (i. e. replugging
the DP cable), but never existed on Windows.

This may mean that signalling between what X.org does and what Windows
configures might be subtly different -- so subtle it doesn't break DDC
data or WIndows display, but big enough to make a difference to X.org-
based display.
