rt2870 wireless chipset

is this chip or will this chip be covered under the rum module? if it 
has not already been started on, i've noticed from looking at the ralink 
opensource driver that it seems be structured nearly identical to the 
rt73 driver. eg: its used in the version 3 of the linksys WUSB54GC 
compact wireless adapter. version 1 was the rt73 which already works 
with the rum module. what i'm asking is, since the two linux drivers 
seem nearly identical; would it be very difficult for me to copy the rum 
driver source to another directory and make the changes evident in the 
linux driver(mainly dealing with loading the rt2870 firmware file) in 
the copied rum driver?

thank you for your insight,

michael
