(if others hit this issue: i have a horrible patch at https://github.com/puckipedia/ossc/commit/3d02b503c637f408ce5d9b1faa77559f71e0b539 which adds one (1) extra bit to the backporch, bringing it up to 10 in total. i can't believe that patch worked. run at your own risk, etc, etc.)
The VESA GTF timings for 1920x1080x60hz use a backporch of (2576-2248 =) 328, which is larger than the current (0.86) maximum that can be configured. This means that the display of the Power Mac G4 I have here, which I suspect uses these timings (as i can't find any other example modelines that use 1118 vertical lines), can't be brought into view completely, cutting off the left side a little bit.
The LCD, connected to the Mac, says:
66.83kHz 59.77Hz
,1080p 1118-p 451748
