Thank you!

This enhancement request was evaluated by the full Red Hat Enterprise Linux 
team for inclusion in a Red Hat Enterprise Linux minor release.   As a 
result of this evaluation, Red Hat has tentatively approved inclusion of 
this feature in the next Red Hat Enterprise Linux Update minor release.   
While it is a goal to include this enhancement in the next minor release 
of Red Hat Enterprise Linux, the enhancement is not yet committed for 
inclusion in the next minor release pending the next phase of actual 
code integration and successful Red Hat and partner testing.

in kernel-2.6.18-138.el5

Please do NOT transition this bugzilla state to VERIFIED until our QE team
has sent specific instructions indicating when to do so.  However feel free
to provide a comment indicating that this fix has been verified.

dump_reimpl feature does not work for me.

# uname -a
Linux z202.z900.redhat.com 2.6.18-149.el5 #1 SMP Mon May 18 22:32:03 EDT 2009 s3

# rpm -q s390utils
s390utils-1.8.1-3.el5

/etc/sysconfig/dumpconf
ON_PANIC=dump_reipl
DUMP_TYPE=ccw
DEVICE=0.0.3732

# service dumpconf start
dump_reipl on panic configured: Using ccw dump device.
/etc/init.d/dumpconf: line 332: echo: write error: Invalid argument

# echo dump_reipl > /sys/firmware/shutdown_actions/on_panic 
-bash: echo: write error: Invalid argument

Seems, there's something is misconfigured or a problem in kernel.

My guess is that you have an older z/VM: dump_reipl is only available on LPAR for newer machines (z9 and above) and on z/VM with version 5.3 and above.
