Hi,
Regarding the videomode I'd like to note that the preferred video mode
isn't
selected because it performs a lot of if checks on the videomode before
setting.
My preferred mode was 1366*786, this is not set because there's a check
that does `if (hdisplay & 0xf) return` here hdisplay == 1366, that's why
the
available modes are sorted and the max possible mode before it is set.
In another case where the preferred mode was 1920*1024 60Hz, it was not
setting the preferred mode because the MAX_BANDWIDTH is 1280*1024*60
and hence the detected mode is the max available mode before it.
