I'd like to add a "me too" to the ARM EABI wishlist.
I'm not sure what the NSLU2 has to do with anything (unless it's the only ARM hardware that you possess?), but if it's a self-contained ARM EABI development environment you're after, feel free to use my virtual machine (http://dietpc.org/downloads/virtual_machines/dietpc3-dev-armel-070209.zip). It's a Debian Lenny ARMEL image...
