I'd say "no" to that. 8-)
"Interrupt line" counters have _some_ device to be associated with,
it's just a question of which one. The problem with doing them with
the current code is that you can't have multiple distinctly-named
interrupt counters per device.
In "my little world," the right thing is to e.g. have ISA IRQ lines
associated with their bus, i.e.:
isa0 irq 0
isa0 irq 1
That opens the possibility for multiple ISA busses in a given machine
(which isn't as far fetched as you'd think 8-).
