for exactly what devices?

you can disable your harddisk's DMA with hdparm, or you can disable it under the IDE setup stuff in the kernel config...

I can only assume you know why you are doing whatever it is you are doing, even though it might be a bad idea...

you can pass these options during boot time and if
that works for you append them in your lilo.conf
take a look here;
read the whole thread.
Sometimes you just need to disable dma to work around
some problems.
