MacResearch

I'm trying to figure out why my mac does not participate in xgrid sharing.

First, I'm a G4, not an x86. If that's the reason, then tell me.

Otherwise:
1. I have xgrid set to use openmacgrid.macresearch.org
2. I has the password set.
3. I have it turned on.
4. Turning it on gives the following in the console:

Jun 14 14:16:35 Kleiman-ibook xgridagentd[21549]: Notice: agent will always accept tasks
Jun 14 14:16:35 Kleiman-ibook xgridagentd[21549]: Notice: agent maximum task count is 1
Jun 14 14:16:35 Kleiman-ibook xgridagentd[21549]: Notice: agent processor speed is 1420
Jun 14 14:16:35 Kleiman-ibook xgridagentd[21549]: Notice: agent will authenticate controller using password
Jun 14 14:16:35 Kleiman-ibook xgridagentd[21549]: Notice: agent "Kleiman ibook" started
Jun 14 14:16:35 Kleiman-ibook xgridagentd[21549]: Notice: agent will connect to controller "openmacgrid.macresearch.org"
Jun 14 14:16:37 Kleiman-ibook xgridagentd[21549]: Notice: agent connected to controller "openmacgrid.macresearch.org" address "134.88.50.44" port "4111"

5. When I close SystemPreferences, the following is logged:

Jun 14 14:16:52 Kleiman-ibook System Preferences[21523]: Admin.xgridAgentControllerPassword: called without first being authenticated.

Alright, what's wrong (if anything) with this log?
What do I need to change?
