Right, that's handles in fbmem.c. Unfortunately, I've never seen it
documented anywhere... So, I've started to write up a doc about
framebuffer kernel command line options. I've come across a few
oddities; among others the format of options:

1. What do the vc: and map: options do?
2. Why can you specify more options after 'scrollback:', separated with
   a ',', but not after the 'map:' option (no other options possible),
   whereas you can have more options following 'vc:', but without a



BTW, anybody have the fbutils compiled for 2k and recent kernels? I
can't seem to get it to compile....
