The info in the VBIOS about your panel is confusing for nouveau, we end up with
*no* valid method for detecting your panel's mode.

Your VBIOS has a 1024x768 mode listed for your panel, and nouveau detects that
it should use it if it's using those mode tables.  However, another VBIOS table
tells nouveau to *not* use those mode tables.  I'll attach
panel-strap-mode.diff to force the use of the tables.

Now, the entry for your panel gives a valid index into the DDC table so it's
possible it reports an EDID that we should use.  I suspect this is probably the
case here, and we make a bad decision on when to use DDC on your card.  I'll
attach panel-ddc-mode.diff for this.

Can you try each patch separately and report which (if any) work for you.

Thanks!
