Haven't read enough of the coreboot source code to be able to say if and 
where those bits are written by coreboot.
They are in the LDN A of the SIO chip, bits 5 and 6 in CR E4h. See the 
SIO datasheet.

Since VRTC is the power well for that unit of the chip, removing the 
power and the BIOS battery for a minute should reset those bits to 0.


I wonder why my mail client doesn't use the address the mails from the 
mailing list are delivered to as address in the from field...
