To enforce certain DMA settings you have to compile your own kernel. See
GENERIC_LAPTOP and look for DMA. You can enforce settings for the
controller and the drives themselves. You should know what you're doing,
though. Of course, you can also download a kernel from releng.netbsd.org
to check whether your problem has already been fixed in -current.
