But not with a 4M ramdisk, I'm guessing, which is what xm-test uses :)

This may be true, however, I am unable to start a 16MB domain with
extra="mem=16M" on x86_64 (x86_32 works). The domain hangs when
trying to unpack the ramdisk. I'll submit a patch that adds the
mem=16M argument to the kernel command line so that it will pass on 32
bit.
If there's something different about x86_64 that limits the minimum
size of a domain, then I re-argue for some sort of arch-specific soft
limit to "help" the user realize that they are doing something that is
likely to fail.
