This reply won't help you, but it should be stated anyway.  8-)

Looking at the ISA dma code, it looks like there is a bunch of code
which really should return an error to the caller, rather than panic,
if it can't get the channel.  Both isa_dmacascade() and
isa_dmamap_create() seem to panic instead of returning an error in
this case.  Really, what I think you want to do in these cases is
return an error, then have the driver that called the isa dma code
either disable the device, or try a different DRQ (if that makes
sense).
