3 in fact ;) and the code is not that much tested yet so we might see more.

I personally see this 3 possible ways:

1) leave it as it is (ie. as what will be commited shortly), this means runtime
checking for osrelease sysctl and behaving according to it

2) introduce option LINUX_24 or something like that to make this a compile time build

3) remove the 2.4 completely saying that "if you want 2.4 emulation downgrade fbsd as well". 
notice that this is 100% ok because linux itself doesnt support 2.4 emulation on 2.6 kernel.

I would go with number 3.
