And that idea I really appreciate it.  From the looks of things though
it does not feel like the distros have caught on.  I know at least that
it has been painful working with SuSE's 2.6.ancient fork when I have
perfectly good code that runs in 2.6.latest.

If the distros will update their base kernel once a year or so I can
seem some benefits to the new dev model.  But so far I have not seen
the updates and when you have to use a distro kernel is seems to
be the same old same old.

Except some features did make it into 2.4.x like native pci-express support.
That is certainly more than just fixes.

Ah another fork that makes support from third parties a pain.  So it
appears Red Hat is going the same way I have observed with SuSE.

I do believe a model where we stabilize features and let them shake out
independently.  Is where we need to go for Linux.  But we seem still
to be at the teething stage and I am frustrated.
