Yes, although I've now got 3 or 4 bug fixes from testing in the suse
kernel that I need to put into the pure 2.4.19 patch.  I'm doing the
last of the fixes today, and I'll start merging back into the main code
on monday.  This was all supposed to happen last week, but I got
diverted by some important other suse work.

If your application is very fsync heavy and doesn't do many non-fsync
writes data=journal will probably be much faster.
