[ale] interrupts in linux??

[Doug McNash]

As a general rule ISA card interrupts are not shareable, 
PCI interrupts are sharable assuming the driver is written 
that way and there is no reason it should not be. Most 
motherboards do have a PCI-to-ISA bridge where they hang 
the keyboard, serial, parallel port and other "legacy" 
devices so those are not shareable if present and enabled.

The PCI BIOS will setup the IRQ's for the PCI devices and 
there is not much you can do to change it.
