TeamCyclops has come out and released a video stating that they were also able to get their CycloDS Evolution working on the new Nintendo DSi

Team Cyclops are pleased to announce that for some time we have had a working test setup which is capable of running CycloDS Evolution on the Nintendo DSi. We must stress however that this is part of our research only; there is still a great deal of work to be done before we can even decide if a DSi compatible device is viable or not. The DSi features a completely redesigned security system which renders all current devices incompatible and at this stage it is unknown if there is any reliable way to overcome the new measures. We will continue our research into the DSi and in the mean time, please see the following video which demonstrates what we have achieved so far.

Like the Acekard, its still a work in progress as they are still finding more information about the DSi and that it is not commercially ready.
