If you want Rockbox on it, then gather as much info as you can (Google the heck out of it, try to find pictures of hardware, detail info) and post it in a post in the "New Ports" thread. Don't just post a request that Rockbox be ported to it in that thread though.
EDIT: Also, I agree, that's a sweet player, but sadly, even if a port was made for it, it wouldn't support near all the features (like bluetooth, on-the-go usb, and all the video formates.) In other words, Rockbox probably isn't the right thing for it. It would be pretty sweet to get linux on that thought...
