This looks good to me, with one proviso: I'd prefer to have the minimum
version be 2.6 rather than 2.4. I think it's quite likely that the
current code base won't work with 2.4.

I'd say we should check the other way round. Namely, that the kernel is
not older than 2.4 and issue an error otherwise. Even though it is
probably unlikely to encounter a kernel as old as that.
The code may have implicit assumptions on certain kernel features only
present in 2.4 or later.
