I think what David means is that v2.6 is the new platform
where all development effort is being done. Most of its core
code, in general, is much cleaner than v2.4.

I disagree with him when he says "v2.4 is dead" (I coudlnt otherwise :)),
because its still maintained and will be for years. And its still in
use by a lot of folks.

But his point is that new development efforts should be based on the
new, shiny, improved v2.6 kernel, since that is where all development
is focused at. And as time passes, v2.4 will get more and more

Unfortunately for 8xx users, as noted by other people on this thread,
v2.6 is not yet 100% (wish it was, I'm myself trying to get our boards
to boot v2.6).

There are some TLB related issue which needs fixing, Panto got a workaround
which works for him (while not being fully optimal). Dan Malek and Panto, at
least, know exactly what still needs work (unlike me).
