As I suppose you are using PC hardware, IRQs greater than 15 are virtual (i.e.
managed by the OS) I think.

But sincerely, I never worked with a PC using IRQs greater than 15, mainly
because I'm still on kernel 2.2.x and using old hardware; so I don't know a
lot about this issue.

One thing that surprises me is that you have ide1 and ide2, while I have ide0
and ide1... usually ide0 is assigned to IRQ14 and ide1 to IRQ15; I would think
that the ide2 could be about a additional IDE controller you had.

So the only thing I can recommend you is to have a look at the BIOS settings, 
usually there are several settings related to the way the video card works.

Hope it helps ;-)
