The current nvidiafb_check_var() simply bails out if the selected mode is out of range of the panel dimensions. A good question would be why the bogus mode is being selected in the first place -- the panel dimensions that are read back are certainly bogus, but alas, I have no idea where to even begin looking at the i2c/EDID/DDC mess: nvidiafb: Device ID: 10de0165 nvidiafb: CRTC0 analog not found nvidiafb: CRTC1 analog not found nvidiafb: EDID found from BUS1 nvidiafb: CRTC 0 is currently programmed for DFP nvidiafb: Using DFP on CRTC 0 nvidiafb: Panel size is 1280 x 1024 nvidiafb: Panel is TMDS nvidiafb: unable to setup MTRR nvidiafb: Flat panel dithering disabled nvidiafb: PCI nVidia NV16 framebuffer (64MB @ 0xC0000000) In my .config I presently have: CONFIG_FIRMWARE_EDID=y CONFIG_FB_DDC=y CONFIG_FB_NVIDIA_I2C=y I've not tried fiddling with these options, as I haven't the vaguest idea what I should be looking at. As a workaround, simply groveling for a new mode based on the probed dimensions seems to work ok. While it would be nice to debug this further and sort out why the panel information is bogus, I think it's still worth retrying the mode based on the panel information at hand as a last-ditch effort, rather than simply bailing out completely.
