Just for the record, with ISA hardware it is impossible to make this
work reliably whatever your software model. I don't think we should encourage
users to try it. I know that the average PC is IRQ-starved but life is hard
and you have to make compromises. In any case the world is moving to PCI and
there you really _can_ share IRQ lines.
