The interrupts are assigned by the BIOS at startup. In your BIOS setup, do you have the ability to assign IRQ's to particular PCI slots? Each system board is different, but most allow you to override somehow. You might have to set the Plug and Play Aware OS (or whatever yours is) to no to enable those options. Some IRQ's that are usually available are 5, 10, and 11. Others can be available depending on your system configuration and what all is enabled. As a typical rule, here's the breakdown:
0: system timer 1: keyboard 2: cascade to 9 3: COM2/TTYS1 4: COM1/TTYS0 5: available 6: Floppy Disk controller 7: LPT1 8: Real Time Clock 9: PCI Steering (bridge to IRQ2) 10: Available 11: PCI Steering (usually available) 12: Mouse 13: Math Coprocessor 14: IDE0 (Primary IDE) 15: IDE1 (Secondary IDE) Obviously if you have something disabled, you can use it's IRQ without problems. Any IRQ's over 15 are virtual IRQ's that are being assigned either through the BIOS or possibly through the OS, although I am unsure whether Linux does this?

I don't understand why the kernel wanted to assign IRQS this way. I guess it's something to do with this APIC technology. Can anyone fill me in here? By the way, thanks to everyone who has contributed to this thread. It's really helped a lot.
