OK, now we have compiled a kernel with bonding function.
Made with LBE based on LTSP 4.1.1.
Manually we configured a terminal to use bonding like this:
insmod bonding miimon=100 mode=1
ifconfig eth1 10.180.1.151 broadcast 10.180.1.255 netmask 255.255.255.0
ifconfig bond0 10.180.1.201 broadcast 10.180.1.255 netmask 255.255.255.0
ifenslave bond0 eth0
ifenslave bond0 eth1
See the result:
-bash-2.05b# ifconfig -a

It works perfectly.
Any hints, how to make the configure at boottime ?
In a rc script ?
