build a kernel
Backing off on 8track kernel build; first I will build for Raven which should be easier. At least, faster.
Ubuntu is at kernel 2.6.35 and DisplayLink driver went in officially in 2.6.37 so a kernel upgrade is the first order of the day.

..or just go for it

Step 4.
In 10.10 there is no fbcon module so I don't need to disable it. I do have /dev/fb0 and /dev/fb1 devices.
