I just read through some of the release notes and it looks like the release notes file for hardware revision "C" references A/B/C. Adding to the confusion, there are instances where one FW version is cross compatible across multiple hardware revisions, but I don't know if that's the case here.
Are there any DNS-323 revision "B" owners who can validate a D-Link hosted source for FW v1.09 (or the equivalent thereof?
