This crops up for me upon restarting ConsoleKit service while logged in. 
Logging out and back in allows the disk to be mounted, as a workaround. Could 
it be something in the policy files in /etc/dbus-1/system.d/* ? So far, I've 
tried commenting out all the "<deny..." items in ConsoleKit.conf, but to no 
avail. I'll keep trying various things, and report back.

Note: this problem went away when I upgraded to f8

Steve, do you start your X session by logging in using a display manager, or
from the console followed by "startx"?

The problem also went away when recompiling hal, hal-libs, and hal-gnome 
without ConsoleKit (removing --enable-console-kit from the configure flags). 

So far, no bad side effects have occurred with our recompiled version, but 
automounting USB keys occurs. Is there any information that would be helpful in 
debugging on F7? 

Unfortunately upgrading to f8 is not an option yet :(

Logging in using the a display manager (GNOME). 

Never mind my last comment, backporting Fedora 8 packages for ConsoleKit, hal, 
and PolicyKit do not remedy the problem. Does anyone even still care about this?

since this works in F8, I no longer care... ;-)

Well for some strange reason, I inserted my USB drive over the
weekend and got some type of non-privilege error.  Has something
broken in f8?

ConsoleKit-libs-0.2.3-3.fc8.1
ConsoleKit-x11-0.2.3-3.fc8.1
ConsoleKit-0.2.3-3.fc8.1

Using a display manager

This message is a reminder that Fedora 7 is nearing the end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 7. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '7'.

Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 7's end of life.

Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 7 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug. If you are unable to change the version, please add a comment here and someone will do it for you.

Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. If possible, it is recommended that you try the newest available Fedora distribution to see if your bug still exists.

Please read the Release Notes for the newest Fedora distribution to make sure it will meet your needs:
http://docs.fedoraproject.org/release-notes/

The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping

Fedora 7 changed to end-of-life (EOL) status on June 13, 2008. 
Fedora 7 is no longer maintained, which means that it will not 
receive any further security or bug fix updates. As a result we 
are closing this bug. 

If you can reproduce this bug against a currently maintained version 
of Fedora please feel free to reopen this bug against that version.

Thank you for reporting this bug and we are sorry it could not be fixed.
