Can you check if you have the same dtrace-problem with -current? I would expect that 9.1 already has some dtrace-fixes regarding new probes in run-time loaded modules, this is just to verify this assumption. Assuming there is some kind of dead-lock in this module-load interaction with dtrace, you could modify the radeonkms module to do it's initialization magic once a sysctl is set to 1, instead of doing this magic at module-load time. This way you could load the module, start the dtrace script and then issue the magic sysctl.
