	Most of the work of implementing PP buffering for KGIcon will be
in fbcon-kgi.c.  The drivers will just get kgicommands set to them a lot
faster |->.  I have a partial implementation of PP buffers written, but
unfortunately 2.2.x does not export to modules many of the functions that
Steffen's pagemapping code depends on.  I am going to take another crack
at it this weekend, and either I will be able to make it work using manual
PTE manipulation or I will have to fork KGIcon to a 2.3-based branch. 
2.3.x has a lot of new memory management and I/O features which would be 
very useful in any case.  We'll see.
