I've just come across this fix and like you I didn't want to install Easy Debian, so I compiled qobi-wmhint-fix myself from source I found on these forums* and found the contents of the fixkdbfocus script through Google, you'll also need wmctrl installed which is in extras-testing. "gunzip" the attachments, "chmod +x" them to make them executable and copy them to /usr/bin (or anywhere in your $PATH should work). *I did come across a binary as well, but it was compiled for Easy Debian and didn't work directly on Maemo.
