Thanks to the efforts made by Steffen, and recently the great work from Daniel(Boinc’s Ubuntu maintainer, and now member of pkg-boinc team) Squeeze will have boinc 6.10.58 \o/.
If you are curious you can see all changes since 6.2.14(Current version on lenny) http://packages.debian.org/changelogs/pool/main/b/boinc/current/changelog
The main feature for this release is that now nvidia and ATI users can use their GPU with boinc(they need to download the non-free libs and apply some workarounds).
And if you read trough here, and you are a boinc user and want to help us, please send an email to pkg-boinc-devel@lists.alioth.debian.org, we need freshblood there
