This is exactly what I've done using the Raspberry Pi (Broadcom ARM SOC running Linux) and a GPS module with the PPS kernel hook for Linux GPIO. Still a beginner/aspiring time-nut so I'm not sure on accuracy (PLL offset jitter suggests ~5-10ms worst-case but I've not looked much into measuring it yet), but it's an improvement on internet NTP at least. (Brief writeup here: http://www.talkunafraid.co.uk/2012/12/the-ntpi-accurate-time-with-a-raspberry-pi-and-venus638flpx/ - - be gentle, it's my first 'real' timing project!)
