thanks for the quick answer.

Your linked to "Maemo 5 SDK". I thought I need Maemo 4 SDK, since I have got a N800 with Diablo on it. Am I wrong?

The newest version of scratchbox doesn't seem to have problems with VDSO32-Support enabled. Right? Is it possible to install the newest scratchbox-version PLUS Maemo4-devkit and stuff?

what would you suggest?
