I made my deposit early January 2008 and didn't hear anything for a few months, which worried me a bit. I then sent them an e-mail and heard I had #217. Maybe you should e-mail them too and ask for your number. The communication department is not the strong point of Fisker (although, in the beginning, when I had a few technical questions, I actually received a personal answer from Henrik!).
I don't know if the 'number-system' has changed after Fisker started appointing dealers and potential customers could also make reservations/deposits there, while at the same time you could still make a reservations directly at Fisker.
Fisker has said they will honor the numbers (except for the likes of Al Gore), but my importer/dealer in The Netherlands already told me that they will let a few 'long time customers' move forward. In all, it won't make much difference because production (starting next months, yeah!) will quickly go up to 1000+ cars per month. So the wait shouldn't be too long, even if some people get preferential treatment. Fisker is not Tesla, where customers had to wait forever with a production of just a few dozen cars per month.
