The limit is set to 512 in order to prevent a non-priveleged user from launching
a denial of service attack on the local machine.

What specifically did not work?
Depending on your distribution, you will want to add options for the dahdi
module on load to the /etc/modprobe.d/ directory to make the settings
persistent. When the mailing list post you linked was first written, there was
only a single /etc/modules.conf file. That single file has been split up into
multiple files in /etc/modprobe.d now.
I hope this helps,
