I'm still not convinced, as every user out there should be falling in
the same trap and we would have tons of reports, not only on ATrpms, or
Fedora, but generally for nvidia closed source driver users on
distributions with nouveau and kernel mode switching (which should
probably be every current distribution out there).

The safest way is to pick the latest running kernel and query rpm itself
how it was done, as the mkinitrd or equivalents are masked behind
wrappers. For example the latest F14 kernel says:

        $ rpm -q --scripts kernel-2.6.35.12-90.fc14.x86_64
        postinstall scriptlet (using /bin/sh):
        
        if [ `uname -i` == "x86_64" -o `uname -i` == "i386" ] &&
           [ -f /etc/sysconfig/kernel ]; then
          /bin/sed -r -i -e 's/^DEFAULTKERNEL=kernel-smp$/DEFAULTKERNEL=kernel/' /etc/sysconfig/kernel || exit $?
        fi
        
        /sbin/new-kernel-pkg --package kernel --install 2.6.35.12-90.fc14.x86_64 || exit $?
        preuninstall scriptlet (using /bin/sh):
        /sbin/new-kernel-pkg --rminitrd --rmmoddep --remove 2.6.35.12-90.fc14.x86_64 || exit $?
        posttrans scriptlet (using /bin/sh):
        /sbin/new-kernel-pkg --package kernel --mkinitrd --dracut --depmod --update 2.6.35.12-90.fc14.x86_64 || exit $?
        /sbin/new-kernel-pkg --package kernel --rpmposttrans 2.6.35.12-90.fc14.x86_64 || exit $?
        
The interesting bits are the second to the last line in this case. But
beware, the scripts' layout can change (they have in the past and will
do so in the future), if you - dear reader in the year 2525 running
Fedora 10^3 - are reading this use rpm -q --scripts to check on how the
initramfs is set up in your time frame. ;)
