How can I remove them? By removing the hardware from your computer.
Should I need to edit the file? What file? If I had to recompiile the kernel what are the things that needs to be removed? I don't know, it depends on what IRQ conflicts you have, you must check that your self. But try what Michael suggested first, he has a good point there. I only looked at the syntax for the entries, not the actual values. Happy hacking.
