The one limitation if you are wanting to run A/UX on the IIci would be that (as I understand it) there is no accelerated video in A/UX. You can, however, still output millions of colours at high resolutions.
In my experience, however, it can help to use a Nubus card from Radius or SuperMac with A/UX for these purposes, as the key combinations that can be used on startup with cards from these manufacturers to force varied resolutions can help the machine to recognize a large monitor. You could try this with the 24AC also, I suppose, as it is essentially a Radius card, isn't it? It may also depend on the monitor in question, but A/UX would give me only 640x480 without this extra (SuperMac-enabled, in my case) "push."
Nowadays I just have my AWS95 hooked up to a 12" B&W, as it mostly only does occasional Appleshare duties and otherwise just sits there looking the part.
