This looks like the same "broken Dell reboot code" issue that surfaced with
RHAS v4.0 U2 and was fixed in U3.

If so, you can use IPMI until it is fixed. Here are some notes from the
time. 

Note, this isn't a fix, you can get the machine to reboot or shutdown but
not both without changing the poweroff_control value below.......

You might also have a startup script that manages IPMI which should make
some of what follows a bit easier to manage. Anyway...

.......

In RHAS. it is possible to use the ipmi (www.intel.com/design/servers/ipmi/)
routines to force a reboot as follows:

Get the latest IPMI drivers
http://linux.dell.com/files/openipmi/

1) /etc/init.d/ipmi stop-all                        [shut down ipmi
2) rmmod ipmi_poweroff                              [unload old mods
.......Change the path in the next line to suit the FC4 install.......
3) cd /var/lib/dkms/openipmi/33.12.RHEL4/2.6.9-22.0.2.ELsmp/x86_64/module
4) modprobe ipmi_si ipmi_msghandler                 [ignore error messages
5) modprobe ipmi_poweroff poweroff_control=2

any shutdown now will result in a reboot.
