2.0.x is more tested, 2.4.x has a lot more features. I haven't seen any
stability problems with the 2.4 kernel in the last time. I think that
most of the development will be for 2.4.x. gcc-2.95.3 is fine, gcc-3.x
should work too. gcc-2.96 from the Aplio distribution has some serious
bugs, I wouldn't use that. You can download a complete distribution with
Web based configuration from http://uclinux.home.at/midori/.
