It would be possible strictly, but whats the point? to compile a module you need to have the current kernel sources anyway... Anyway, the kernel part needs some fixing to make the PCI nodes pollable for IRQs and just use the standard SIGIO mechanism for async notification. Once that is done I could make a module version of it that will provide a character device that allows any kind of IRQ signalling to a sufficiently privileged task. The only problem here will be in systems that support reconfiguration of PCI IRQs on the fly, but we can probably just ignore that case. PS.
