Hi, 
 
Is there some clever way to poll the retrace status? Basically I want a couple of variables to be set when the display hw is in retrace, and cleared again when not. I'm using interrupts for this right now, but if there's a way for me to avoid that, I'm all ears.

	What's the anti-troll code?   That's your personal code to be able to add comments and messages on the dhs.nu site.
  Don't have a code or forgot it? Fix it here.
