This is a problem. We also parse it to find the DFP EDID and/or
flat panel informations, do that work with the real ROM ? I don't
know much about x86 BIOSes, but at least for the DFP EDID, I suppose
that one is read in RAM by the BIOS, not in the ROM...

You may want to look at the version I have in my tree
on ppc.bkbits.net/linuxppc-2.5-benh. I don't have much time
to sync with your before a couple of weeks for now... This version
rely on my Power Management stuffs I posted earlier that James didn't
seem to merge yet though.

The ChipIDs aren't in the documentation. I suppose the best source
here is the XFree driver.
