In a German TV show a SuSE representative said that in the next
distribution they will support reiserfs. It was not completely clear,
but I had the impression that you will be able to boot from it too.
The distribution is supposed to come out in a month or so. Earlier
this year they also stated that they plan to move into the Japanese
market with their own distribution.
I have used the journaling reiserfs for a while now and I didn't have
any problems. I didn't do any benchmarking, but performance was ok and 
after crashes it is nice to have a journaling fs. Not that linux is
crashing a lot, but if you do some driver developement you get a crash 
once in a while :).
