I removed the usleep() call there and now switching the channels works
*much* better than before:

There are still problem when I'm too impatient and switch to the next
channel before the image appears on the screen (no turbo-zapping ;-) ) but
now I just have to do a "make rmmod ; make insmod" to get the card back to
work. Earlier today, I often had to reboot the PC to get things working
again. Thanks for the tip!
