please check if your port may use v4l_compat

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:
