You can't just drop a driver source package in the kernel source tree and hope it compiles and works. Nor can you drop a binary driver on the filesystem and expect it to load into the kernel (the modules framework is very different between Linux and FreeBSD).
If it's not listed in the ports tree, then probably not. Check the output of:
Code:
# cd /usr/ports
# make quicksearch name=kmod
to see which drivers and other Linux "modules" are known to work. Most of them, though, as for USB web cameras.
