and this means currently it's not possible to install any rhel-5 i386 
server with more then 2GB or ram from kickstart when any of the packages 
require any kmod package:-(
because in this case anaconda will choose kernel-PAE by default (and 
this will be the default entry in grub). and if bar requires foo-kmod, 
then it will pull _only_ kmod-foo which of course pull normal kernel 
(but still the default will be kernel-PAE). and either you'd have to 
change grub's default and only use less memory or manually install the 
required PAE version kmod packages:-(((
