No - not poking fun and I don't believe that any user should have access to
interrupts.  This programme is compiled/run as root.

With good reason :)

I tried checking the source code of svgalib - if it's going to remain as
difficult as it seems I may find a simpler project.

I was hoping that there would be a simple method of getting permission from
the kernel for this operation and for direct access to video memory/registers.

Thanks for the reply Marcus.
