My pomona clip had issues with its contact pins(the ones in contact
with the flash chip) over time, so I unmounted it and repaired it.

The cmos layout is in src/mainboard/lenovo/x60/cmos.layout

Example in grub.cfg:
menuentry 'Normal' {
        cmosclean 0x30:0
        cmosclean 0x30:1
        cmosclean 0x30:2
        cmosclean 0x30:3
        cmosclean 0x30:4
        cmosclean 0x30:5

        halt
}

Vladimir Serbinenko said me that it was a bad idea to do this and that
he would instead work on something better that would understand the
coreboot cmos layout. I've not checked if there is now something for it
in grub.

Denis.
