If it really boils down to ONLY displaying a new image any 10 minutes, then you will probably be able to drive that from a 586 server... there is not much processing power involved then on server or clients, and not too much data sent over the network neither. Having the rotation will not be a problem. You already figured how to do that, and you have a working Xorg.conf. Save that and use it in LTSP for the clients. There is an appropriate lts.conf setting to use a pre-set Xorg.conf instead of autoconfiguration. The rest is getting autologin setup, and running a "display manager" that is basically something like the "xli" program, with a SIGHUP sent whenever the source file needs to be re-read. You probably have that running already from the local machines, so porting that to a server will not make large a deal.
