Upgrade problem 6.1 -> 6.4

[Alex de Kruijff]

I wanted to upgrade to 8.0 to take advantage of the USB code. I've run
in to a compile problem going grom 6.1 to 6.2.0. I've copied sys/dev/twa
from 7.0 in to the source of 6.2. Without this source it will not boot.

I"m clueless at this point, any help would be much appreciated.
