That was something I was wondering about also, and meant to do a search.

Hmm, a google search doesn't immediately show *why* it's the default in 
Fedora, and I haven't been following LKML for the last three months so I 
don't know how it's been fairing against the deadline and AS schedulers 
lately.

It was merged into 2.6.6, but it looks like fc2 has been using it longer 
than that.
