Well you will probably be using wvdial to access your isp. I believe that this had the option to do multi-link. I think its just a simple change in the script. I could be wrong though. I read up on it some on
http://www.tldp.org
and the modem guide said that multi-link support had to be compiled into the kernel, so it maybe some kinda kernel module, but I dunno, that doc was kinda out dated. The newer kernel may have it already. I would just check out my wvdial and see, You could also use other gui dialers in KDE, or Gnome
