There are only two ways we can find the correct fixed timing that is suitable for the panel this device use - either from the BIOS, or from the EDID. DDC fails, and no EDID returns. Apparently the modes read from BIOS is also broken..

I think the patch in general is ok for sanity check purpose, so should send to mailing list for RFC.

Nuzhdin Urii, you need to report this to the HW vendor of your device...
