We employ a small army of highly qualified QA and engineering people to
do that. It's very very hard work. In addition we make choices that suit
our business customers but would be very bad for progress if they were
the "base". To a lot of our customers progress is evil unless they can
schedule it six months in advance. 

If the base kernel worked that way we'd not have gotten a useful OS yet.
Don't confuse the deployment goals of big business and the developer
goals of the community. If you stand in the middle you get stretched
into strange directions and eventually (as we found with the Fedora v
RHEL split) you can't do both at the same time.

It always depends "at what". 2.6.10 is more stable than 2.6.9-ac at SCSI
and USB for example because the backports were too complex.
