In addition, many ISA bus drivers do not use the DMA API *at all*
currently. If you want to fix them all up, great! But somehow I doubt
those will get fixed in the next decade.. they've been like this for at
least half a decade or longer :-)
Point being, if this doesn't already work it's likely a bug even without
this patch. And drivers that don't use the DMA API should at least be
allocating memory with GFP_DMA which should fail if that zone doesn't
contain any memory (and if not, that's likely a bug as well).
