no certainly not, we haven't yet discussed the release kernel.
options are 2.6.25 or 2.6.26.

you omit the interesting next paragraph:
"Building the new drivers is only for advanced users (who for example
want the better speed of firewire-sbp2 relative to sbp2) - and for
distributors who know what is required in userspace to make use of the
new drivers and who can get bugfixes backported and rolled out quickly."
on the kernel side we do backport firewire patches.
for the userspace side i still see lack of action on libdc1394
"2008/01/05: The official version 2.0.0 has been released.
2008/01/05: A first set of fixes have been released (version 2.0.1)"
why is that not even in unstable/experimental?

the progress of the juju stack is very nice, there are quite some
fixes queued for 2.6.25, we will make those snapshots available
soonest.
if the regression list for 2.6.25 is still high we may reconsider
there to build the old stack with blacklisted modules.
that has always been our stated fallback position, currently in the
development phase we encourage testing of the newer stack
on latest linux-images.
