I do not believe that Red Hat enables the JFS module and that if you
build your own kernel, you lose support on that kernel.

[ewilts at pe400 boot]$ egrep 'CONFIG_.*_FS is not set'
config-2.6.9-22.0.2.EL
# CONFIG_REISERFS_FS is not set
# CONFIG_JFS_FS is not set
# CONFIG_XFS_FS is not set
[plus a whole bunch more]

I did this grep on a RHEL rebuild so the options might not be the same
as a stock RHEL build, but I think you'll find that JFS is not enabled.
