Black is supported, but LCD7 cape is not.

Not sure how to reproduce the jumping on pen-up. I was able to draw

Is there any particular pattern you want me to test with?
I would still like to test with a more recent kernel on LCD7 cape. So,
if anyone has ideas (other than I porting the LCD7 support) please let
me know.
