I've got 4 boards: D975XBX2, DX38BT, DX48BT2, DP45SG but unfortunately,
I can't reboot any of them to get to the BIOS right now.

I don't think this is a good idea. The driver is meant to expose the
asc7621 itself and not the specifics of the motherboard on which it is
installed. In this case, since temp5-8 are the PECI bus temps, future
boards and/or future BIOS on existing boards could easily enable them.
In fact, older BIOSes on the D975XBX2 and DX38BT boards disabled PECI by
default, so temp1 was the actual CPU diode temp and not the temp
relative to thermal throttling as it is now.
