Just smack this guy.  His argument is completely pointless.  What does
"driver support" get you?  You're ordering the machine, right?  Then only
order hardware that is supported.
You need to start out by pointing out that this guy is arguing with no
ammo himself.
The "obscure" argument can be defeated by showing the number of big
companies that use FreeBSD, companies such as yahoo,, etc.
Also, by claiming "there is no difference between the Linux and FreeBSD
kernels" your opponent is basically saying "I don't know what I'm talking
about".  For better or worse, there are tons of differences between the
two kernels.  You could just start perusing the code and pointing out
differences and debunk the guy.

You could do some searching on the NFS exploit that Linux had a short
while back that FreeBSD never had.
