That's what I'm using on these routers.

Either openwrt or gentoo-mips folks.
It seems to me that there is a chance that gentoo-mips will have more
apps ported than openwrt (which doesn't really have many applications

Have you read qemu 0.8.0 changelog? It was released a couple of days ago.

Whatever slow it is, it will be faster than trying to compile anything
natively on these tiny routers :)

So, this means, that if I build a whole gentoo-mips under qemu - sounds
easy, doesn't it? :), with mipsel uclibc stages/-march=mips32, almost
each and every binary copied from such a system should run on these tiny

I never intended to run gentoo on these tiny routers.
I just thought that compiling/porting software for openwrt/mips on
gentoo-mips would be easier than compiling software for mips on a x86
system (I'm really not a cross-compiling expert; and not everything is
ported to openwrt).

Now I see why it didn't even start.
