I was needing similar thing for KNotify (see KNotifyConfig::readEntry in 
kdelibs/knotify/deamon)
(But my implementation in KNotify is specific for KNotify)

The idea is to have subgroup:

[foo]
...
[foo/A]
...
[foo/B]
...
[foo/B/bar]
...

And to move up in the hierarchy when looking for a key until we found it.
