Hi Samjlee,
I ran the 10_4 pkg which installed successfully since as you found, Cosetup crashes.
I left for my meeting defeated because Shareport Util said I was connected, but there was no indication of that in Finder. But, after doing nothing beyond that (besides wasting my time in a meeting), I came back to find that it was indeed showing up in finder and easily accessible.
Songbird would not let me access it as a music library (presumably due to it's massive size), but I could open files album at a time (roughly 200-300 MB flac files) in VLC and play them. Note that I did experience glitchy playback, but due to the fact that my small office shares the wireless from this router, I am guessing that it was a bandwidth issue, not a Shareport issue.
As I write this, Shareport is not able to connect without giving an error message, a ghost of the HD is stuck in Finder, I cannot eject it, I cannot Force Quit VLC, nor can I force restart Finder. So as soon as I click "post" I'm gonna hard reboot and see if I can duplicate anything positive and hopeful that I achieved today regarding shareport

FWIW, an NAS is by nature a far more reliable and flexible device for media sharing and storage, and would be my default solution. I am pursuing this for my media storage because (A) it's a nice feature to have on a router I like well enough to have bought regardless of it's USB port, and (B) it's a very handy way for me to have access at no additional cost of an NAS to my music library when I'm working at a location in the building other than my desk.
I think that D-link probably does consider it to be important to support Mac users, but given the tremendous devotion of resources to finish the project, maybe it's hard to make it a top priority. As a guy who has a zillion "top priority" projects in motion at any one time, I can't fault them too much. Someone who bought the router (perhaps you?) specifically for this feature is more than entitled to feel differently.
Let's keep our hopes up! I think we'll be pleased with it in the end. I'll check in tomorrow and report more results.
