this change was correct, but you missed em28xx-i2c.c, and please do
not use my v4l-dvb tree.. it's a fork of the maintree 11 months ago!
My v4l-dvb-kernel tree is the right one for these experiments.
Let me know if it works out by adding
EM2800_BOARD_PINNACLE_PCTV_HD_PRO     to em28xx-i2c.c

You should also name the device EM2880_BOARD_PINNACLE_PCTV_HD_PRO
instead of EM2800 (since em2800 is a castrated version of the evolved
em28xx series).

cheers,
Markus
