I don't know his the dual booting works on phones, but wouldn't partitioning the system partitions be the way to go?
I'm not saying that this is the correct answer, just some knowledge I picked up in the Desire forum with custom HBOOT.
If you had a ROM in that standard desire system partition that was only 100mb,you were wasting another 150mb because the system partition was 250mb.
So people flashed a custom hboot #system partition # to gain maximum space.
The issue is though, soon as you change the partition size, data has to be moved and is often corrupt.
So you needed to restore a Nandroid to get all the data back.
I only say this because what if you partitioned the system partition and not mmc?
Could you not find out the default partition sizes, partition to those sizes and try flash another Rom. Though that does assume your phone will even be read by the partition software.
