I personaly don't have an ARM9, but I do know that Creative Zen players use MTP. Armarok media player has support for MTP, and you could also try Gnomad2.
if you are running Ubuntu
Code:
sudo apt-get install gnomad2
or for fedora
Code:
sudo yum install gnomad2
otherwise you can get the source code here.

hope that helps
