Does anyone know what I would have to modify in 6 if I wanted to run on an older Pentium M CPU without PAE? Is it just the kernel that needs to be rebuilt (maybe while installed in a system with a supported CPU)? Or are there other components that would cause problems and need to be rebuilt too?

generically, you'd install the kernel srpm, and modify its rpmbuild scripts to change the HIGHMEM64G kernel configure option to HIGHMEM4G ... I would also change the name of this kernel (I'd add -noPAE to it, I think), and the builder name, then run rpmbuild.

specifically, I haven't done this in quite a long time, so would have to figure out the details as I went along.
