Quite a bit of the 1.9.92 development was done on an nc6320, so this
platform should work well...

Ah, you've got the 1400x1050 screen. We've been seeing several reports
where that resolution isn't working right. We'd love to have you help
out here if you're willing; you'd need to fetch current driver sources
from git and compile them though.

Alternatively, you can wait for RC3 and hope that we've magically fixed
this, we have been working on exactly this problem and things are
working for more people today than last week when 1.9.92 was released.

The log file confirms my suspicions; the clock of 108MHz used for the
LVDS is higher than the BIOS will let run in single channel mode, but
not higher than what 1.9.92 will run in single channel mode.

Thanks much for reporting this issue; please let us know if you're able
and willing to try building from sources to see if current bits work.
