You'll have to 'coss install' -- put the disk in a machine with PAE
support and install it there, load the kernel srpm, rebuild and install
the kernel, etc. and then install the disk in the original machine. It
might be possible to cross rebuild the kernel and use a kickstart file
to deal with the kernel issue, but I am not sure how to do that.
