The patch has nothing to do with latency. It tries to enable *different*
zaptel drivers to synchronize with each other.

Please read more carefully the paper you referred to:
1. Zaptel has no problem with different cards handled with
the *same* driver.
2. With different drivers, each gets its own clock from the
interrupts generated by its cards. They are *almost* the same.
3. Because of the slightly different *frequencies* a packet may
sometimes be lost (not big problem for voice).
4. Fax/modem may get disconnections as a result of this loss.
Yes, this is true.

* I hope now the problem is clear.
* Xorcom fix does already work.
* Anybody (including you) are invited to improve it or
implement a better one.
* That's how free software gets better.

First you ask "Is it true?" and than you are confident enough
to call other people by names...
Let's stop trolling. Anybody is more than welcome to use/not-use this
code. People who understand the problem are more than welcome to suggest
concrete improvements, etc.
