I've never heard of dMSN, but have you heard about Gaim? It's an fast application which works with ICQ, AOL, MSN and god know which more protocols it can handle. I don't know which distribution you are using, but most of them (at least the ones I use, Slackware, Redhat) are shipped with Gaim in the install disks. I think you could give it a shot.
Anyway, gaim homepage is here:
http://gaim.sourceforge.net/
Good luck
