Well, I am running a RH kernel, the latest 2.2.16-3SMP RPM. But, I do not
have the kernel source on the machine.  However, I do have the kernel
headers so that drbd will build :-)

I have just built drbd on a stock RH 6.2 SMP build on another machine (got
SMP machines comin' out my ears, y'see :-), and it built fine and loads OK.

So, I am mystified at the moment, as I can't see which include it is
getting the version info from.
