iOS 4.2.1 And Ubuntu 10.10

Despite whatever people say, iOS 4.2.1 (8C148) is not working on my Ubuntu 10.10 AMD64.  It's able to mount, to see everything that is there (i.e. read only) but I simply can't sync it.  No way no how.  This is the conclusive reference for me as of now.  Based on what I read, it's because of libgpod.
