The latest mkreiserfs tools (3.x.0k-pre) have finally put use into the
s_journal_block_count field.  They renamed it to s_journal_magic,
though, and put a random number in it.  GRUB's reiserfs driver was the
only program looking at that field to get the number of journal blocks
(and I even asked the reiserfs journalling guy if relying on that
field would be safe) :(

I fixed grub in the CVS repository.  Or you can apply this trivial
fix:
