Way cool.  

The next step is to write functions that implement the methods
(callbacks, funciton slots, whatever) which rcons needs: basically
blitting, and scrolling.  If you can write the console font onto the
card's memory, i think you can just copy the relevant rectangles.

Both 1.3.2 and -current first produce kernels in ELF format, and then
convert them to a.out and ECOFF.  a.out is bootable by the scsi
boobtlocks.  ECOFF is bootable via the PROM tftp (or mopd, if you have
an Ultrix server).  You don't need a corss-compiler.
