iPad 1st Gen issues

My app is crash free on iphone3Gs and up (including the supported touch devices).  But, on the first generation iPad I get a lot of itermentent crashes (app closes down).  Note, this not a native iPad app. I'm only supporting the smaller mobile devices, but the iPad can do its little 'iphone app simulation' and that's when this is occuring. 

I'm compiling with 3.2, and using GPU mode. Though, to be honest I don't think it is relevenent. From what I can tell, the crashing is occuring during Garbage Collection.  I know this because (at the moment) I force System.gc at certain points (in between screen transitions). It doesnt crash all the time, but a good 50% at certain areas in which there tends to be a lot of garbage clean up going on.

So, anyone running into similiar issues?  Interesting work arounds?  Rumors that all iPad 1st Gens are going to vanish from the earth so I no longer have to deal with this?

Thanks
