New port linux-gspca-kmod, a usb webcam driver based on the linux

driver 'gspca' (from http://mxhaard.free.fr/index.html) built on
FreeBSD using devel/linux-kmod-compat . The driver supports a very large
number of webcams.

However, THIS IS EXPERIMENTAL CODE, TRY IT AT YOUR OWN RISK.

This is only for 6.x/7.x and at the moment only for i386.

Most bugs and limitations are due to linux-kmod-compat rather than
this port itself, so upgrading linux-kmod-compat (and rebuilding
this port) will most likely improve functionality and remove some bugs.

As usual if some of the port gurus wants to help fixing any mistakes
that i may have made in the port (or missing things, e.g. a suitable
warning message when the port is installed), i will be very grateful
(and can spend more time working on the emulation code).
