If compiling a kernel is required and too daunting, then there's
rpi_gpio_ntp: http://www.vanheusden.com/time/rpi_gpio_ntp/
Initially only for raspberry pi but I noticed I made it generic enough
to work on all linux systems with pps via gpio.
On my rpi the jitter is between 2 and 10us iirc but it is a while since
I tested it. A quick peak shows me currently 3us jitter. Not bad for a
userspace solution imho.
