I'm using vic with pwc.ko. Since vic uses MMAP, it works only when
pwcbsd is built with MMAP support. I tried both linux-gspca-kmod and
linux-ov511-kmod with vic. But, they didn't work. It seems neither
linux-gspca-kmod nor linux-ov511-kmod support MMAP.
I need following patch to work Logicool Qcam for Notebooks Pro:

The vic's configure tries only /usr/include/linux/videodev.h. So, we
need following patch:
