Ok, this is promoted mode (Promoted to 31KHz).
There are 2 problems:
Horizontal display end position (DIWSTOP) is _much_ farther than real end of display, for some reason it is after horizontal blanking which makes no sense. This can be compensated so that display looks better but..
Problem 2: Both horizontal DIWSTRT and DIWSTOP do not match bitmap's edges at all (lots of empty space in both sides, I assume it has something to do with mode promotion, "normal" modes are exactly matched), autoscale can't position this correctly.
-> Better option is to disable mode promotion (sys:prefs/icontrol)
