The overall robustness and "niceness" of the code is also a totally different
story now. 2.6 software architecture is definitely better, and many drivers
are much more stable. Implementing board support and drivers in 2.6 is also
much easier and cleaner than in 2.4.
to strip both kernels of all unnecessary drivers and features
that could hamper performance. If you wish I could try to dig up the .config
