Ok, if I understood you, you want /usr/src/linux to point to the source tree of the kernel you booted with? I'd use the "local" init script and a switch in bash that correlates uname -r with a particular directory. Each case then sets the symlink.

Same thing, but instead you'll be changing a symlink in /etc/modules.autoload.d. Normally you only have 2 files there: kernel-2.4 and kernel-2.6. However, if you're going to be switching among 2.6 kernels, make kernel-2.6 a symlink, then have it point to files in the same directory, each with a unique name for each kernel you have. Then just use the same switch statement for the /usr/src/linux link, and have each case set the modules.autoload.d symlink as well.

Well, you could automate this with the module-rebuild package. Are you talking about rebuilding modules every time you switch kernels? If so, I'd just have a bunch of different directories in /lib/modules.
In any case, all of this would be a lot easier if you make sure each kernel has a unique version string.
