There's something odd with the first 8 pixels on each line for me --
it looks like there's a faint line down the side. I'll try to fix it
tonight, but I don't make any promises.

I haven't noticed this, but I might have just not noticed. It the
effect very pronounced? There are a number of timing issues, and I
don't have a very good feel for when I need to put delays in the
system. I guess I'll try adding a 100us pause before every I/O access
and see if it fixes anything.

Hmm, try something like this (untested). You might be better off with
a cron job taking pictures instead of a picture-on-demand system.
Also, remember that there's no locking done right now, and weird
things will happen if two programs try to access the quickcam at once.
