Right now the framebuffer drivers are mapping the framebuffer into the kernel

way there would be a single point of remap for all framebuffer drivers.  It
would also let all of the high mem access code be localized into fbconsole if
the fb was mapped high.

This would also get around my problem of using framebuffer drivers but not
using framebuffer console. In my case I don't have enough kernel address space
to do the remap. If fbconsole is doing the map, then the kernel map will never
happen on my system since I don't load fbconsole. 

I looked through a couple of drivers and none of them seem to touch the buffer
after it has been remapped. They only pass the pointer back to fbconsole.

What about
  - read from/write to /dev/fb*?
  - the logo code?
