Assuming you find one thats electrically compatible and organized the same as the original, it will at least boot. Then you can work on getting the extra memory to be recognized.

Okay, getting a replacement shipped might take some time but putting it on should be pretty quick. What needs to be done to the bootloader and firmware source to see more ram? Is there any part of that source that hardcodes the ram to 8MB?
saratoga:
The memory size is in the configure script, firmware/target/arm/as3525/memory-init.S, and probably some other places. Theres no AMS target with >8MB of RAM so you'll have to dig around a bit.
funman:
You'll probably also need to change the SDRAM settings in memory_init.S
The registers are described in the datasheet for the PL172 memory controller and the settings should be provided by the SDRAM chip manufacturer.
good luck :)

Don't get me wrong, this hack is cool by default.
But may I ask why?
