Belkin provided the source code as specified by the GPL. I was wondering how hard it would be to upgrade the kernel from 2.4.30 to 2.4.37.7. I know that 2.6 would be extremely hard because the driver model has changed so much. But, what changes happened between .30 and .37 that would make it difficult to upgrade the code? Did the driver model or other drastic changes happen? Could I just do a file diff; import the new files Belkin added and update the make files and kconfig? The CPU and wireless card are based on the Ralink 2880/2860 or something like that. Justin Madru
