This *might* help a bit - it won't prevent the icon from being
displayed but it won't ask for the password, instead putting up a "Not
authorised" message. 

Create a file called what you like with the extension .pkla and stick it
in one of the directories in /var/lib/polkit-1/localauthority - I used
50-local.d. The file should have the following contents:

[Disable Mount]
Identity=unix-user:*
Action=org.freedesktop.udisks.filesystem-mount-system-internal
ResultAny=no
ResultInactive=no
ResultActive=no

It worked for me. If you find a way of disabling the icon as well
I'd be grateful if you could let me know.
