i'm curious about the rules for removing code like this.  in the case
of drivers, isn't it possible that some driver source could be
relevant for both the 2.4 and 2.6 kernel source tree, and simply uses
that kind of preprocessor check to make sure it's being compiled
appropriately?

or are you doing something more sophisticated than simply checking the
kernel version being tested?
