An example of this is that the serial driver is hard coded to report

It does an autodetect sequence to find the ports. If it reports ttyS0-S3
your system probably has them, they may just not be wired to external
ports and that is kinda tricky to autodetect

looks for everything again anyway. In a more friendly system X would
use the info the kernel provides and automatically configure itself
for the devices present or hotplugged. You could get rid of your
xorg.cong file in this model.

Not really as half of xorg.conf is preferences

I think what he wants is that you could have preferences, but that something functional if not optimal would be selected. What would actually be useful is if the kernel would provide a small report of the video hardware in some useful format, such that (example) /proc/somthing/video_config could be included in the xorg.conf.

Yes, a number of distributions build the xorg.conf at install time, although it's sometimes wrong and can't readily be made right after the fact. And really should come from kernel info found at boot time, I believe.
