[PlanetCCRMA] rt kernels, ho, ho, ho!

I can confirm that it is the b43 driver that is causing the boot hang. I 
blacklisted the b43 driver module, and then was successful in booting 
the rt kernel.

I am not familiar with the recent changes in the Broadcom firmware. I 
only recall reading that Broadcom had released it as open-source. I will 
need to look into this further. I have a rpm package that contains the 
firmware, that I made for Red Hat 5, but it worked in Fedora 10/11. I 
see if that will work.
