These giant tables of modes are insane.  Especially having a bunch of
different refresh rates when the LVDS actually has a fixed refresh rate.
Just generate a mode at each appropriate size using GTF or CVT.

I'm not really sold on the whole idea of the kernel generating these
fake modes for LVDS, given that we can support any size and that the
refresh rate is a lie since we're always using the fixed mode.  Any
other opinions on this?
