Comment 6 Adam Okuliar 2010-11-12 18:08:05 UTC
we successfully tested  initscripts-8.45.30-3.el5_5.1 on RHEL5.5 on
Linux ibm-x3650m3-02.lab.eng.brq.redhat.com 2.6.18-194.el5 #1 SMP Tue Mar 16 21:52:39 EDT 2010 x86_64 x86_64 x86_64 GNU/Linux

When adding:
BONDING_OPTS=" miimon=100 mode=4 lacp_rate=1 "
into /etc/sysconfig/network-scripst/ifcfg-bond0

bonding driver is successfully loaded withou affecting /etc/modprobe.conf. We tested bonding driver against Cisco c3560e both with two and four interfaces in port-channel and only two cables connected to server. In both cases bond0 remains in bridge after reboot. 
Closing with verified status

Comment 7 Ondrej Hudlicky 2010-11-12 18:09:10 UTC
Reproducer used for verification:
1. show the switch ports configuration, to declare how did we configure the ports, four in one bond or two in one bond.
2. to check whether the bonding work without modprobe.conf alias setup
3. to confirm whether the bonding work with BONDING_OPT setup in ifcfg-bond0
