I was going to leave this one alone, but your getting way off track now. A
virus using "unused" CMOS RAM to store itself is crazy. Sure, some systems
do contain 2KB or more. But the keyword here is *SOME*.

Now apart from anything else, if a virus did install itself into CMOS RAM,
a standard system could in no way execute code out of CMOS, therefore it is
no longer a virus. About the only thing it could do, is corrupt this RAM,
which is typically used for BIOS configuration settings. That's probably
enough though. RAM timming Chipset features etc, etc would be effected.
