Woooo Hoooo!!!! I got it to work!!!!
Suggsy, yep tablet is definitely rooted.
I tried your 4.0.4 RC1 firmware, the firmware is really good but it still didn't recognise my camera, so I installed Christian Troy's pwn3d-1.4 from SlateDroid and Bam! it recogsied the camera immediately and wanted to download images...

I have tried Remote Release app and DSLR Controller app and I very pleased to say they both work fine
I think the problem is a usb driver issue, I ran an app that said it couldn't find a certain usb driver on the stock firmware, unfortunately I can't remember what it was called at the moment
srthomas, it may be worth trying the pwn3d-1.4 firmware, it worked for my Canon cameras, maybe it'll work for Nikon too...
