the closed source drivers usually have two pieces, clearly seperated.  
one piece is open source and interfaces with the kernel, the other piece 
implements the hardware specific features (be they wifi or 3D graphics 
or what) and is called from the 1st piece, and is supplied as a closed 
binary module.

its my understanding that there's NO traces of any linux kernel in 
ESXi.   the RHEL that was in the original ESX was the management 
console, which ran in VM0 (much like dom0 on a Xen system), and wasn't 
the hypervisor.       What I saw poking around a esxi4 install looked 
more akin to a stripped down BSD, with a BusyBox shell.
