Reading your mail, I just wanted to try whether simpler user-space mips
emulation would let one run NanoNote applications directly:

 mkdir rootfs && cd rootfs
 fakeroot tar -xzvf ../bin/xburst/openwrt-xburst-qi_lb60-rootfs.tar.gz
 qemu-mipsel -L $(pwd) -E LD_LIBRARY_PATH=./lib \
    ./lib/ld-uClibc- ./bin/busybox

Unfortunately, for me that segfaults (Ubuntu 10.10 x86_64/qemu 0.12.5).
I had already success with that method running ppc or arm binaries on an
Ubuntu x86-64 box.  Would be a nice tool to run and debug
openwrt-compiled applications immediately without going through the
image-regenerate + qemu boot steps.

Anybody got that working?
