While I think I understand why you say this, it very easily can sound 
like a monopolistic tactic to sell more Sun hardware. 

You start with "Well, aren't our binary kernels good enough" .. which 
next turns to "Well we don't support vendor X's raid controler with our
binaries".. next on the list is "Well, we QA everything on Sun hardware"

I think you will have a defensible case for "Use our binaries" when you
can support patched Debian and Ubuntu kernel packages, and there's been
discussion on the debian-kernel list about the merits of the patches.
