Hello.
Most cases take place because kernel doesn't support blocksize != 4096.
I don't have any ideas why fs with standard journal created by ' 
mkreiserfs -f -h r5 /dev/sdb2'
is failed to mount. Would you please send us the kernel messages?

What manpages do you mean? My 'man mkreiserfs' says the following:
      -b | --block-size N
              N is block size in bytes. 4096 only for now.

Because of restricted set of standard errors..

try the following (using your date) under root privileges:
cat /var/log/messages | grep '^Oct 19 17:3' | grep reiserfs
