Would think that this bug 17823 which includes a patch, wouldnt need much modification to fix this bug too.
The patch from bug 17823 only assigns a serial to drive C (or to be more precise, the drive where Windows is installed). Currently Wine stores them in a ".windows-serial" file located in the corresponding drive directory, but that would not work for Z: or any other drive where the user has no access. Properly fixing this issue for all drives would require to store it somewhere else (for example in the registry, based on dev/inode?).
