To port over all of the QuickCam stuff you need to:

Instead of ioperm(),  you just want to say:
open ("/dev/io", O_RDONLY);

Take all of the outb(x,y) and change to:
outb(y,x);

Remove Linux includes, replace with:
#include <machine/cpufunc.h>


Also, I would suggest on waiting to make ports for the QuickCam 
software--  It's in a heavy state of flux right now, and new releases 
are very frequent.
