If a PC bios is assumed hacked, then following Gregs advice earlier would make any data on the PC compromised.
One should assume this is the case, agreed. But this would also be true for your original idea.

The chips your links refer to, are not PIC chips; PIC chips have very limited capabilities and resources ... PIC18F4550 chip.
Actually, Sergei P. Skorobogatov explicitly refers to the PIC18F series as having known vulnerabilities.

BTW, if some of the 256 bytes of PIC EEPROM was unusable(due to a hack resident), it would be noticeable,
Skorobogatov refers to several forms of attacks which are non-invasive (that is, not noticeable).
