Well, the CPU slowed to a crawl when I used level with motion sensors is
why.  For a few days the svn kernel worked like crap due to it until I
changed it back to edge.  So while this isn't a very satisfying
explanation, I took from these experiences that I should use edge and
not disable interrupts when dealing with drivers on GTA02 and then
things would work :-)
