Rockbox Ports are now being developed for various digital audio players!
This is somewhat unrelated to the Zen Vision M, but you may enjoy reading this. It's a patent from Creative for "controlling distribution of protected content." (see http://www.freepatentsonline.com/20070014403.html) I was looking on google for "creative hash algorithm" and various other searches (who knows, I figured it was worth a try).
Oh no its encrypted and hashed many times by reading that. Best way now it seems is literally to dig through the code of the firmware updater (as it says its encrypted when transferring to the device), and/or the code of the bootloader.

Assuming the vision W and M are the same in terms of firmware upgrades, it seems that any checksumming done by the player is done using code stored on the player's ROM, as the HDD can be changed out on the vision W without any problems. http://onemansblog.com/2007/07/20/tutorial-how-to-upgrade-the-creative-zen-vision-w-hard-drive/
