This was something that I was worried about -- it seems like this sort
of thing would negate any benefit from building a database of panels for
general use.

Perhaps it would be posible to build a database of panels as described
in their datasheets. Boards which have a CPLD could perhaps define a
per-board fixup function, since they know the sync lines are inverted or
whatever.

I'm not sure though -- my experience is with our board which has a
PXA255 and no CPLD messing with the display controller stuff. I'm wary
of coming up with a solution which is only useful to me and noone
else...
