Yes (at least I think so).
I believe the problem is that the halt script resets the NIC when
doing a soft shutdown, disabling the Wake On LAN.
The fix for me on Fedora FC6 was enable WOL near the end of
eg (the first two lines are the new ones)
be careful and good luck.
#Set the NIC for Wake-On-Lan
/sbin/ethtool -s eth0 wol g
# First, try kexec. If that fails, fall back to rebooting the old way.
[ -n "$kexec_command" ] && $kexec_command -e >& /dev/null
[ -f /poweroff -o ! -f /halt ] && HALTARGS="$HALTARGS -p"
exec $command $HALTARGS
