Hi Tony,

RHEL55 will soon rebase to systemtap 1.1 which contains the fix, so 
there are currently no plans to backport the fix to 1.0.

If you need to backport to 1.0, I would be happy to help with any 
problems you may encounter. To help get you started, I've attached a 
list of the changes needed to complete the fix.

Please use the public mailing list (systemtap@sources.redhat.com) for 
any further questions.

Thanks,
Dave
