Let's see if I can word this so it won't come off flaming (pilot light,maybe).
The original post did not say (nor imply) that the virus would DO anything
(ie. executable code) within the CMOS once it got there.
If we accept that the author was only asking about a virus that would
WRITE to the CMOS RAM, then I think your conclusion that there is no such
thing is slightly off base.
Judging by your signature, I'm sure that you know a lot more than I do 
about invasion programs (call them virus or trojan or whatever) but I have
heard of at least one "strain" that attempts to change the CMOS data.
