Pretty sure I've seen other cases where r128 gets the panel size wrong. We do something similar in the vesa driver though, where we'll call out to the VBE panel ID method if there's no EDID. I'd be interested to see what vesa does on that hardware. The panel size dump in r128 is scraping out of some scratch registers that happen to be the right size sometimes, where the VBE call might actually be reliable. - ajax
