-Xms sets the initial memory allocated. You probably want -Xmx, which 
sets the maximum amount of memory that will be allocated, and you 
probably want this to be fairly high, or at least more than 48m.
If you're going to patch the makefiles, a clean way to do it may be to 
add like a variable JAVACFLAGS, which we can then set in the ebuild like:
use amd64 && JAVACFLAGS="-J-Xmx256m ${JAVACFLAGS}"

I'm pretty sure it's a blackdown on amd64 thing. We do encounter it for 
a few packages, like net-p2p/azureus. For the record, there is a amd64 
version of sun-jdk-1.5 (and 1.6...), but I'm sure at this point I 
shouldn't have to go into the concerns about using them ;)
