You will run into problems with a 2.4.0 kernel.  But  that  does  not
mean  that  you  have  to  use HHL 2.0. The kernel source tree is one
thing, the (cross) development toolchain is a  different  issue,  and
the  native  tools  used for the target is yet another story. OK, the
(cross) development toolchain and the native  tools  are  related  in
some  ways  -  at  least  they should use the same versions of shared
libraries, etc.

But you can easily  use  a  more  recent  kernel  source  tree  while
continuing  to use the your current tools - if there is nother reason
to change.

They weren't that important. They were merely at the top. The  people
who  really  run organizations are usually found several levels down,
where it's still possible to get things done.
