Xorg error messages are poor.

If we wait for Xorg, yeah, it's probably years off if it'll come at all.  But 
it doesn't have to be that way.  Look at knoppix!  I haven't looked into how 
they do it, but I'm imagining an X wrapper that detects the video card(s) and 
runs from a dynamically built xorg.conf based on that and certain user 
configuration options.  If, say, it's an nvidia card, it first tries 
the 'nvidia' driver if it's available.  If it fails it falls back to nv and 
finally to vesa if necessary, or to a fallback xorg.conf devoid of 
user-defined options, or to an previously established known-good xorg.conf.  
If all that fails the user is presented with a human-readable summary of what 
failed and recommended next steps.
