You must be referring to "bonding" or "EtherChannel". I have tried it in 
linux. What you are saying can't work, becouse:
bonding, creates a seperate virtual network interface, which is the one 
with the combined speed. THIS is the one you assign your IP to. The real 
network interfaces aren't assigned any ip, they are used directly by the 
bonding driver.
What is more, this technology cannot be used for connecting a single 
computer to multiple networks. It is used to connect to another SINGLE 
device, which uses the same technology.
The only way that I know of, is using BGP on BOTH sides of a routing 
device, and set both metrics to the same value, for the default destination.
I am pretty sure that BGP is not offered by any provider here in Greece, 
except if you a corporate customer, for example buying several megabits 
of bandwidth, using a leased line.
Maybe linux's policy routing could do the task. But I haven't tried 
anything even remotely similar.
A few month I asked my Cisco instructor for that same problem. He told 
me that it CAN be done, but it SHOULDN'T be done, becouse it is not 
stable, by design.
