LCD monitors auto-adjust if video uses standard timing.  Grml fb1280x1024 uses
nonstandard timing.  The mode reported by "fbset --info" does not exist in
/etc/fb.modes or any standards.

Framebuffer is VBE 2.0 so it cannot change modes like VBE 3.0.  It can be
impossible to get the console output centered properly.  A few lines at top of
screen are lost.

The most standard timing is 60.020 Hz vertical refresh.  It is old, but the most
common.  A faster refresh standard is 75.025 Hz.

The wish item is to alter fb1280x1024 to match standard timing.  Since LCD
monitors are indifferent to refresh, it does not hurt to use standard timing
values.  Example, see table on page 50:
