You're right.

The difference is hardly noticeable with most practical uses.

Not yet (unless you update the relevant packages yourself, of course,
in which case it won't be official Owl).  You'll have to wait a few
kernel revisions more.

For us, the significant difference between 2.2 and 2.4 at the moment
is that I haven't reviewed 2.4 kernels for my usual set of potential
security issues, yet.  I did that to 2.2 between 2.2.9 and 2.2.13, and
as you could have noticed this has resulted in 2.2.13 fixing quite a
few security issues.  I have no reasons to expect 2.4 is in a much
better condition now.  We've already seen several security fixes that
were applied to 2.2 over a year ago still missing in recent 2.4's and
finally getting applied just now.  The ELF loader integer signedness
and overflow issues are a recent example.  We had them fixed back with
2.2.14-ow2 (January, 2000) and 2.2.15+.  Now someone re-discovered
them still not fixed in 2.4 this July.

That I can understand.  I avoid using reiserfs, though.
