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.
