I hope you don't take the "reverting" part too personally.
The patch I uploaded that you tried was create before this bug report was
filed, and it was really meant for Bug 91966.
I have seen the developer for r128 (ATI Technologies Rage 128 based graphics)
change his code to activate VGA even if it was not detected via I2C bug.

https://cgit.freedesktop.org/xorg/driver/xf86-video-r128/commit/?id=562681414f38c6925da01b3fec0802f532cd9e53

Perhaps, I can change the code to remove manual VGA detection code, and just
assume that a VGA monitor exists even if VGA monitor was not detected via I2C
buses.
How do you think?
