This behavior (reinstalls show different IRQ values) is caused a feature 
called IRQ Steering. By using PCI bus IRQ steering, Windows can dynamically 
assign or "steer" PCI bus IRQs to PCI devices. There is a Knowledge Base 
article that describes this behavior:

Description of PCI Bus IRQ Steering (Q182604)
http://support.microsoft.com/default.aspx?scid=kb;EN-US;q182604

If you need to disable this feature to force a specific device to use a 
specific IRQ, see:
