I don't think you understand what is meant by patching.

For example, I built a 2.4.23-pre5 kernel at the weekend, and did some
heavy CPU and disk stress testing on a cluster.
As these are Opteron machines, I applied an entire patch set from Andi 
Kleen at SuSE, in order to get a working kernel for x86-64
These patches are publicly available.

IBM may be applying patches to use one of their filesystems -
but I seriously doubt if they are using closed-source code.


What we SHOULD maybe be discussing in the Linux community is
binary-only drivers. 
For example nVidia or the VIA drivers for their MPEG decoder.
Class, discuss :-)
