BTW: I still have systems running which are older than Core2, one

an Intel PIII 550MHz (and keeps good time as a stratum-1 server with

I guess that it would qualify for a low-power processor these days, so
who cares about managing its power and messing with its TSC?
;-)
Low-power in what sense? Work done, or watts consumed? <G>
I would still very much like to have a low-powered (watts) system
running NTP perhaps with a good (for timekeeping) FreeBSD version.
Something the size of a home router, with a serial port for the GPS.
Looking for better than (say) ten microsecond accuracy. About US $100-150.

I think that that the closest you can come "off the shelf" would be a
Laptop. You are not likely to find one in that price range.
PHK has created GPS clocks using a "single board computer" and a GPS
receiver. I don't know what it cost him. See:
