Really? More than one active DMA at a time just killing the machine
completely?
The good news is that ISA DMA is broken anyway, and it might just be an
acceptable option to not even have a "BROKEN_DMA" config option, but
just unconditionally refusing to allow two concurrent ISA DMA streams.
The only things I know of that do ISA DMA is the floppy and old sound
cards, and if that means that the sound skips while accessing the floppy
I don't know if we really need to worry too much..
