For OS2007 there's simple-launcher, but there doesn't seem to be a OS2006 (standard 770) version..
Another one is 'idea', which does the job slightly differetnly. I haven't tried it, but it's supposed to be available for both 770 and N800 (OS2006/OS2007). Check in your application manager if you already have it. Unfortunately the one-click installation system (where you click on an 'install' icon on a maemo web page) doesn't handle dual-OS installs, but extrapolating from the OS2007 setup I would guess on manually adding the following repo to the application manager could do the trick:

http://repository.maemo.org/extras
distribution: mistral
components: free non-free

Then update and look in the installable applications list.
