That is not the problem. If you didn't fiddle with your pam config running as root should work. You can add such a group by following Clark's suggestion. Do you run a vanilla Debian system? I guess the kernel was created by you as I'm not aware that Debian's kernel support gumstix. Can you provide your .config in that case?
