Unfortunately, I spoke too soon earlier today. I have discovered I am unable to mount my device as a user. I am able to mount both "main memory" and the SDCard as root. This is with version 0.6.29, the last version documented to work with glibc <2.9. I was able to mount the device filesystems as an unprivileged user with 0.6.19.

Perhaps related, I get errors with calibre-uninstall too:
root@galactica: /media
·*¬ calibre-uninstall
Invalid invocation of calibre loader. CALIBRE_CX_EXE not set

Additionallly, calibre_postinstall isn't clear if the udev rules installation was succesful:
