Similar for the DRM ioctl, but it requires a privileged client like the
X server to enable the interrupt. How is that handled by the svgalib
kernel module? Also, I suspect that the svgalib module relies on a BIOS
whereas the DRM has no such dependencies.

It might be a good idea to write a small library which uses any of these
means if present, so apps can easily take advantage of them.
