Lilliput DisplayLink monitor

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
