I have a Creative ZEN 8GB model. It has a different chip, but likely very similar firmware. I have opened it, and the chips I could see, are as follows:

CPU:
Sigmatel STMP3760
BBE-TA4
UO4211
072956

Memory:
Samsung 734
K9HBG08U1M

(Two of these)

According to Sigmatel's materials, the STMP3700 class chip uses an ARM 926 as the core(300MHZ), with built in USB, DC conversion, headphone and microphone amplification. It as well, contains support for WiFi, and Bluetooth, however the Creative ZEN does not have this hardware...(yet). If you need more information/pictures, let me know! I will be happy to provide.

Could you take some pictures and/or use a (flatbed) scanner to take some hi-res scans of the main board?

Zeroth:
Be glad to. Opened it while I was at work, I'll post pictures tonight. I have also extracted the firmware for the ZEN out, it looks similar to the ZVM firmware, however, I don't know how to use zenutils zen_crypt on it. What do I need to do, to decrypt the firmware?

EDIT: I just found this: http://linux.sigmatel.com/, which contains a modified version of linux and the requisite toolchain for the 36xx series chips, and likely contacts for the 37xx series chips. :D Hardware programming in this case is likely quite easy.

UPDATE: I have the scan... its very highly detailed(1200 dpi... so quite large...)  Anyway, here is the link: ZEN chip scan Any other help I can provide, please let me know. I am familiar with C, a bit of hardware/software programming, and assembly(unfortunately, MIPS not ARM)

mcuelenaere:
I made a wiki page with all the information I could find.

Since it's a wiki I would say: go ahead and edit it! ;)
