I'll let James comment on this particular point, this is beyond my knowledge. However, I talked with him a bit about the bad resolution detection for the LVDS panel with kms_branch. It would be nice if you can provide a dump of the registers while in the virtual console (that is without X running). You need to give the --enable-viaregtool switch to the configure script, then once built and installed, run 'via_regs_dump -dpm' and post the output. It would help to enhance the LVDS resolution detection code.
