Setup your Interfaces

iface bond0 inet static
        address 10.10.199.5
        netmask 255.255.255.0
        network 10.10.199.0
        up /sbin/ifenslave bond0 eth0
        up /sbin/ifenslave bond0 eth1

Setting up the Modules

edit /etc/modprobe.d/arch/i386 and add 

alias bond0 bonding

once you have added that, run the following to update your modules files. 

# update-modules

Finished

now running ifconfig, should show you something like this. 

# ifconfig

Troubleshooting

bond0: No Such Device

If you are seeing something similar to the following, then the modules file is probably not correct. 

# /etc/init.d/networking restart
Setting up IP spoofing protection: rp_filter.
Reconfiguring network interfaces...ifup: interface lo already configured
SIOCSIFADDR: No such device
bond0: ERROR while getting interface flags: No such device
SIOCSIFNETMASK: No such device
bond0: ERROR while getting interface flags: No such device
Failed to bring up bond0.
done.

In my example, I wrote "aliad" instead of "alias" 

# modprobe bond0
WARNING: /etc/modprobe.d/arch-aliases line 6: ignoring bad line starting with 'aliad'
FATAL: Module bond0 not found.

After correcting the spelling, remember to run 

# update-modules
