Attached a patch. It will:

(1) make isa-bus maintain isa irqs, complain when allocating
already taken irqs.
(2) note that (1) works only for isa devices converted to qdev
already (floppy and ps2/kbd/mouse right now), so more work
is needed to make this really useful.
(3) split floppy init into isa and sysbus versions.
(4) add sysbus->isa bridge & fix -M isapc breakage.

Hi Gerd,

This looks great! I have implemented isa_reserve_irq() on top of this.
It allows one to reserve ISA irqs without converting them to qdev, which
for certain interrupts makes sense, and I have also made the other users
call it until they are converted to qdev.

Let me know what you think. With this I get what I am after.
