Upon loading of heci driver it prints a list of discovered module guids. QST guid is 6B5205B9-8185-4519-B889-D98724B58607. But I have mostly gave up on development of this driver (although I keep using it). I think that it's better to port either OpenSolaris or Linux heci driver to FreeBSD. BTW, Intel has released QST SDK source code: http://software.intel.com/en-us/articles/Intel_Quiet_System_Technology_Software_Development_Kit/ -- Andriy Gapon
