Grrr... I mean if I remove "1680x1050", it works fine (in 1280x1024) mode
in 24-bits deep. In other words,
Modes "1680x1050" "1280x1024"
results in a 1280x1024 h/w resolution with a virtual size of 1680x1050 (and
doing the ctl-alt-minus would not switch h/w resolution modes).
If I use:
only, then it comes up at the right h/w resolution with the same virtual
