Uh, so it sounds like you're telling me that /proc/fb is essentially
useless for autoconfiguring the X server.

1) /proc/fb reporting something doesn't mean you can just switch on
   "UseFBDev", because that won't work with "generic [kernel] drivers"

2) people using "generic [kernel] drivers" could use any X server video
   driver, potentially, so their case works the same as people who
   aren't using a kernel framebuffer driver at all

This is extremely disappointing.  It makes successful X server
autoconfiguration essentially a crap shoot.
