Here's a debdiff for Lucid.
It seems like Debian isn't using any kind of patching system, so that's a patch directly applied to upstream code + it's changelog entry targeted at lucid-proposed.
As for maverick, I believe that this bug should be fixed upstream and will then be pulled from a new udev in Debian without needing any ubuntu-specific release (as udev is currently synced from Debian).
