It's actually a good sign.  It means my EST changes work on your laptop 
and so est0 is attaching.  The downside is that it is attaching instead 
of acpi_perf0, which happens to have more info about your system.  It's 
difficult to fix this without an architecture for ordering the 
probe/attach of all cpufreq drivers.  This is not easy since we have no 
general mechanism for drivers bidding for the same hardware identified 
by different methods.

Until I can figure out a more general way, you can just set this in 
loader.conf:

hint.est.0.disabled="1"
