this is wrong, and imo, unnecessary.  it's wrong because using DMA gains a lot 
of speed increases, and works for in many cases (i haven't seen cases where it 
didn't work, but i haven't been actively developing in the last year of 
course).  it's unnecessary because there's already a CONFIG_xxx option to 
disable it if your platform is having problems and you can't figure things out, 
and don't need the speed gains.
