Also, is it not possible to defer this operation until we've parsed the
command line, control it with a kernel boot parameter?
I thought of that, but it seems a bit complicated to me to parse boot
options in assembly so I left this for another time.
Well I'm wondering whether we can instead do this query later on, after
we've entered start_kernel().
The query is done while machine is in real mode (in arch/i386/boot/video.S).

The firmware EDID is only used as fallback, or if drivers have no DDC/I2C
support. Currently, all drivers that use the firmware EDID also have I2C
support in place. And chances are, if DDC transfers failed, the firmware
EDID will also be absent.
hm.  Don't you think `default y' would be better?  As it is, people's stuff
will mysteriously stop working.
Hmm.  You're right, 'default y' looks better. Would you like me to send you
a patch, or would you rather take care of it?
