i've got two of these, one for my CD32, and one for my poorly A4000.
the CD32 has operated just fine, rock solid display, did give me a couple of heart stoppers with a completely blank display, but that was just down to the CD i was using. let it boot to the rom screen, and everything's fine.
The A4000's ill at the moment, so i've not installed and tested it yet on that machine.
one thing i did notice, and this also for the Indi Mk2's for my A1200's, it sets up something mental like a 1536x980 screen for the boot screen? not sure. anyway, this may be a cause for what i've heard, some people's screens to go "signal out of range". However, i've not expirienced this issue, and i'm pleased with it, it's an amazing difference over composit/scart upscaled, and zero video banding at all, unlike what i have seen occasionally with using VGA.
but like others i guess, i'm waiting on the new core for more normal screenmode goodness
