Loongson-specific instructions haven't implememted now. So, if want to boot a linux kernel, we should built a 32bit one and drop -march=loongson2e compiler flags. For simplification, please use the kernel patch (for 2.6.33) in the attachment and then use arch/mips/configs/fuloong2e_defconfig to compile a kernel. Besides, the disk image I used is debian-lenny built by you which is available at http://people.debian.org/~aurel32/qemu/mipsel/debian_lenny_mipsel_small.qcow2.
