According to the follow-up in:
http://lists.digium.com/pipermail/asterisk-users/2007-September/196556.html
current zaptel 1.4 SVN solves this.

Thanks for the quick feedback.

I can get ztdummy.c from there in a patch, but I rather just wait a week
or so until 1.4.6 is released.

Note, however, that elsewhere in the thread Chris Nestrud reported he
had the same issues with kernel 2.6.21 . The current support for hires
timers in ztdummy is only for kernels >= 2.6.22 because a specific
symbol was not exported before that (hrtimer_forward).
