Speeding up NetRain response times for 5.1.

We have Tru64 5.1 with patch kit 006 installed.
And have two 100 BT FD (ee0 and ee1) cards configured for NetRain.
NetRain is working fine except it takes too long to switch from a
failed NIC to a good NIC. Initially, this time was ~40 seconds. I've
tweeked the NR settings and the fastest I can get is 7 seconds. I need
less then 1 second.

I did not see a patch for 5.1 for this. However, there is a patch for
5.1A and 5.1B and the release notes state that it is possible for less
then 1 seconds response times for NR. I'd really not like to upgrade
to 51A or 51B as this is more risky.

Here is the /etc/sysconfigtab entries for NR:
netrain:
nr_timeout_t=1
nr_timeout_o=4
nr_timeout_dead_interface=2

Any help appreciated.
Thanks,
