Retina assets causing problems on iPad 1

I've just overhauled an iOS iPad app to bring it up to retina resolution. It's almost entirely bitmap-based and relies on a lot of fullscreen background images.

 

For the (separate) iPhone version, all assets are at retina resolution, and everything works just fine with the default StageScaleMode doing all the downscaling for older devices.

 

Not so with the iPad version – the iPad 1 can't cope with some of the larger backgrounds, and gets very crashy very quickly, even with the Resolution set to 'Standard' in the publish settings. It works perfectly with iPad 2 onwards, of course.

 

So, my question: does anybody have any tips to optimise my way out of this? I'd rather not have to swap in different assets and coordinates for every display object and animation.
