I tried with a Radeon 9250. This time dexconf got the monitor right,
it did not include bogus refresh rates and limited the resolution to
1280x1024 by explicitly naming some resolutions in a display
subsection.

After removing this subsection the problem was the same: a mode larger
than the physical resolution was chosen.

I tried installing the new driver (looks like only 1:6.7.192-1 is
available by now) and this time only the ddc modes were used. However,
the log messages do not look too reassuring. The built in modes are
rejected because of bad clock/interlace/doublescan, nothing is printed
about screen physical resolution.

Thanks
