I'd be really carefull here. Once users start repartition their NANDs it will 
be nightmare to troubleshoot problems.

My experience with NAND is that it often fails to mount correctly. So you have 
to repeat boot until you succeed. But then it works ok.

uSD works perfectly on GTA04. It's faster then NAND, you can buy big SD card. 
I am daily using GTA04 as phone - it runs from ext4 on class 10, 16GB uSD and 
never had single problem with it. I'd go for uSD.

Btw have you seen rowboat[1] project? They have android 4.0 for beagleboard. 
It should be very similar to GTA04.
