# get the kernel sources into /usr/src/linux-2.6-2.6.22
# e.g. apt-get source linux-image-2.6.22-3-amd64 or so
# apply patch, compile & install

# ntp:
apt-get source ntp

cd /usr/src/ntp-4.2.4p4+dfsg

change ntpd/refclock_atom.c line 287 from:
        up->pps_params.api_version = PPS_API_VERS_1;
to:
        up->pps_params.api_version = PPS_API_VERS;

CFLAGS="-I /usr/src/linux-2.6-2.6.22/include/ -I /usr/src/linux-2.6-2.6.22/Documentation/pps/" CPPFLAGS="-I /usr/src/linux-2.6-2.6.22/include/ -I /usr/src/linux-2.6-2.6.22/Documentation/pps/" fakeroot debian/rules binary


There's one problem though:
13 Jan 17:44:49 ntpd[16226]: refclock_atom: time_pps_getcap failed: No such device
