What are you trying to do ?
Probably not without heavy modification. That firmware is looking for certain pieces of info that comes back from the hardware. So unless you can modify it to look for the returns that your pc can give it it won't work. You would be better off either looking for an opensource software to do what you want or just writing your own code.
Thats what i thought im sure ill find some linux software thanks for the fast reply...
. I don't know if any of these WRT54G emulators will work or not, but it looks like a good place to start.
