It's in CSSU-Dev which I don't use either (I use CSSU-Thumb). So what I've done is, temporarily add CSSU-Dev repo to Fapman, tap Upgrade applications, select everything with certman in the name and 0.2.3 in the version number, ignore everything else, run the update, remove CSSU-Dev from repos, close, reboot. It might or might not be the recommended way but it worked fine for me.

I don't know about Marble (I tried it once but could not get my head around its UI), but e.g. modRana works and does not time out like Nokia Maps.
