linux emulation

[Da Rock]

I've read the handbook and just about anything on linux compat under
freebsd. I am particularly interested in drivers under linux compat.

1. How do I install the drivers for all users under linux compat?
2. Is it possible for freebsd programs to use the linux drivers?
3. Anything I should be aware of before I embark on this adventure?

In particular, I'm interested in drivers for multimedia cards and input
devices.

Cheers
