Device drivers for Linux2.4

Hi,

This question is not specific to IA64, but may also be useful for 2.4 kernels in general: is there a place where the differences in the implementation of drivers from 2.2 to 2.4 is clearly explained? Because for the moment all I have been doing is catching the problems while compaling, looking at the others' code, and modifying mine from this... I know that there are some changes that are being made every day, but... Is there a repository where I could have the precise list of them?

Thank you by advance

Geraud
