This increased the size of the base binary and the GUI theme files probably by quite a bit (although some of them can be turned of during compile time). While three radio buttons certainly don't take up much memory, the code to implement them, added atop all the other new code, may very well have filled up many hundred of kilobytes.

Many hundreds of kilobytes will effectively kill the DS port unless the 
new code can be #ifdef'd out.  I doubt that is the cause here though.  
There's perhaps a megabyte or more of free memory at the first screen of 
Monkey island, and nothing that's been implemented should take that much 
RAM.  If it is, it's being done the wrong way!

Yes, that will be great.

Thanks,
