I'm having similar issues to Jabba and am also running 3.2006.49-2.
I've tried installing lxdoom, crazyparking and a few other games that are dependant upon maemo-games-startup.

If I install from http://maemo.org/downloads/product/doom/ it will install the 1.4.5 version of lxdoom for me. The opening screen with a "Play" button will appear but will do nothing when you push it. If I run lxdoom from the command line it tells me that libshadow is missing. Other maemo-games-startup dependant games are similar except for the libshadow comment on the command line.

I've tried installing maemo-games-startup from different repositories but either it won't load or will corrupt the games such that strange text appears in the place of the word "Play" on the play button. I don't recall which versions I used but I may have mixed and matched poorly!

For those that have it running (nosam or whomever else might be browsing), is it running on version 3.2006.49-2 of the OS, and if so did you load any prerequisites (eg maemo-games-startup, maemo-games-startup-dev) which version of lxdoom AND the prerequisites are you running? (I'd like to know the versions as I've already corrupted the games with obviously incompatable versions of maemo-games-startup, and though I'm fortunately booting from MMC it's still a pain reinstalling the OS from internal flash to MMC to ensure a clean image).

The versions I've seen are:
