Fact of life - on a 2.4 Linux kernel for x86 or PPC the timer
resolution is 10ms (look for the HZ macro in

Anyone using ztdummy on a 2.6 kernel is using precisely the same
software timers which drive the kernel's POSIX timer s

Steve's original link for why software timers are a bad idea was from 2002.
Since then we have had fantastic improvements in
a) cpu performance
b) latency of the kernel
- anyone tried the low la
Using zaptel just for a time source is silly. We should use POSIX timers
instead. Here's a start, but I don't know how long it'll be before I can
get to finish it, so I thought I'd post it here in the hope that someone
else will pick it up.
This demonstrates how to set up POSIX timers to interrupt
