If you're using the linker script from CVS it should be ok. And while hello.o is 4000 bytes long the bss section can be larger than 16K since that is not part of the file image.
look with arm-elf-size

I think it is impossible with the current lwip/ppp code (they could get improved sizewise in the future).As for other boards depending on how much memory they have you can fit in either lwip or the more complete freebsd stack with ppp. At least 128K for the former case and more (maybe 512K ?) for the latter. Try building the app you want for existing ecos targets then look at how large they are and pick one target that fits your needs.
