Using the actual VGA retrace interrupt (which doesn't exist on a lot of cards), or by fiddling with the timer interrupt? I tried to write one a couple of months ago, using the timer, and ran into all sorts of problems. I got it working 90% of the time, but it conflicted with any VESA calls I made, and also screwed up when I tried to access the disk. I still haven't figured out why :-) I have some examples of regular timer, mouse, and keyboard interrupts, if you want to take a look at those.
