ISTR this unit is based on an ARM running uClinux (no MMU) on an ARM9 chip... hence, you should be able to get kernel source from Netgear.

I had a play with one at CES and the software sucked much harder than the original receiver stuff IMO - 5 seconds to skip to the next track, for example. Might have been pre-production though, so don't take my word for it!
