Sweet. Any other tips? I'm hoping to apply the AF_BUS patch to the Linaro kernel for the Freescale iMX53 Quick Start Board. The patch isn't accepted upstream in mainline for some reason, even though it speeds up dbus by 2x. In any case, rebuilding the kernel on the board it self is, well, time consuming.
I've set up an armel chroot with debootstrap (great tool) and I've copied a qemu-static-arm binary into /usr/bin so I'm hoping that working in that chroot will speed things up a bit. But any other advice you may have would be warmly welcomed. :-)

But were you writing assembly in a hex editor?
