fatalsaint, here's what I get when I become root and run an “apt-get remove vista” command:

Reading package lists... Done
Building dependency tree

You might want to run `apt-get -f install' to correct these:
The following packages have unmet dependencies:
osso-software-version-rx34: Depends: flash-and-reboot (= 3) but it is not going to be installed
Depends: initfs-flasher (= 0.95.16-200823maemo2) but it is not going to be installed
Depends: kernel-diablo-flasher (= 2.6.21-200823maemo3) but it is not going to be installed
Depends: libbz2-1.0 (= 1.0.3-1) but 1.0.3-2 is to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
