With serial, NE2000, IDE support. Tested in big-endian mode.
Memory size hard-coded to 128M for now, so don't play with
the -m option.

+Qemu is a full system emulator. See
+
+http://fabrice.bellard.free.fr/qemu
+
+Limitations & comments
+----------------------
+Supports the "-m mips" configuration of qemu: serial,NE2000,IDE.
+Support is big endian only for now (or at least this is what I tested).
+Derived from au1x00 with a lot of things cut out.
