I forgot to look if the README is the right one, but ...

I think that's the problem. There was a patch to Qemu on April 23 to add flash support
to the qemu_mips target. Now you have to do qemu-system-mips -pflash filename. Just copy
u-boot.bin to filename before.

If it says something like " invalid flash size 0Mb " after DRAM: 128 MB then it stops
that's definitely your problem. Use SVN HEAD from Qemu instead of 0.9.1.
