Unless the rpm implementation in Suse is very different to RedHat's its
not quite that simple to work out what rpms are not required.

One of the problems with dependency resolution with rpms is that an rpm
may provide a library and that library may be required by a another
package, but the rpm query will not pick this up.

rpmA provides libA
rpmB requires libA

rpm -q --whatrequires rpmA

will not return rpmB

for that you need
rpm -q --whatrequires libA

For each package in the list generated, you need to query the rpmdb for
what they provide and then for each of those check that no package
requires them.
