Another +1 - I've done bonding on Linux servers across different switches
many times.  The last time the switches involved were stacked 3750Gs
allowing me to do etherchannel on the switch side.

The bonding module has a few parameters that can be tweaked to suit your
situation, but the setup is straightforward.  I've done something similar
on a Windows server, but it was handled by the NIC driver rather than
being part of the OS.
