run profiler when high cpu

I want to have profiler run for a period of time - 5 minutes - when system
cpu exceeds 90%. This would happen automatically. Can this be done?
My suggestion would be to add an alert to Performance Monitor to detect the
> 90% CPU, and then have it execute 'the relevant SQL' to start a
server-side profile. See
http://vyaskn.tripod.com/server_side_tracing_in_sql_server.htm for the
latter. The '5 minutes' would just be a case of storing the trace start
time somewhere, and having a SQL job that runs intermittently that stops the
trace after the required time.
