I have tested the driver back when I wrote it.  Not sure why it worked
then, maybe the chip in my notebook back then didn't care about
alignment or I just got lucky with the memory allocations.

My old test hardware was likely thrown out in the last move, about two
years back.  Performance sucked anyway, 400kB/s was the limit.  Maybe
we should just remove the driver and not spend any more time on it?
