 I suspect people are getting pretty tired of me posting "I can't reproduce
 that" comments.  But, I can't reproduce that.  I grabbed build 608, build
 a new kernel from the olpc-2.6 git head, and it worked just fine.  So I
 patched in the current version of the driver, and it worked just fine.

 I cannot reproduce the image quality problem either way, of course.

 Do note that you need to bring in the new ov7670.c along with cafe_ccic.c.
 They're a set.

 I'll send Andres a patch so that we're at least all working with the same
 version of the driver.  Then we can keep trying to figure out just what is
 going on here.
