modutils? Thanks, found! There was a file + symlink without package...

The easiest way is to wait for 2.6.24 to appear in backports.org and to add that to your sources.list. Instructions are on www.backports.org. It's also possible to add unstable to your sources.list and to install the kernel from there. A new kernel generally has very few dependencies. So this should only pull in few other packages from unstable if any. If you add unstable to your sources.list and don't want to upgrade to unstable you have to configure apt to use stable by default with 'APT::Default-Release stable;' in your apt.conf.

Probably the most significant addition for powerpc in 2.6.24 is CONFIG_NO_HZ support, which may help reduce CPU power consumption when the system is mostly idle.

Generic kernels include drivers for all sorts of things, most of which you don't have. This can reduce the size of the kernel, which can translate into faster operations, as well as reduced space needed to hold it (and the modules you build, if any).
