fb: nvidiafb: Try harder at initial mode setting.
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.
