The GTA02 rootfs should work, but the GTA02 kernel won't run in qemu
(or rather, it will run and detect GTA01 hardware, because that's
what's emulated). So GTA02 kernel hacking is not the best choice if
you have no hardware. (Contributions to qemu-neo1973 are very welcome
It was chosen to not put effort into faithful emulation of GTA02
hardware because it makes no difference for application developers,
while the kernel/u-boot developers had not really made use of qemu
during the making of GTA01 (except for Cesar Barros' cpu-freq support
and minor bugfixes by me - fixing nasty kernel/u-boot bugs is what
qemu is best at). Currently only the parts of GTA02 that had no
equivalent in GTA01 are emulated.
