It should be possible to repackage it to use /opt more. I may take a stab at that in a few days (newyear's eve holiday). I unpack and repack on my Linux desktop computer, which is Debian-based and thus has all the required tools. The important ones are 'fakeroot' and 'dpkg-deb'. The latter is available also on the N900 itself, but the former is not. It may be possible to avoid needing it by actually being root while repackaging, but I haven't tried this. In any case, if you try this on the N900 itself (e.g. because of lack of a Debian Linux desktop/laptop environment) then you should do this on an ext3 partition, not vfat, otherwise the package will not be repackaged correctly. Oh, and remotely logging in to the N900 with a proper keyboard and screen would make it easier. ...
