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. -mike
