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...
