Ugh. Please use --disable-kvm on such old kernel versions. KVM doesn't work on G4s (yet) anyway.
I guess I'll need to add a minimum version check for KVM on ppc.

Same as above with the difference that PPC64 can actually use KVM. So if you like to use KVM, please update your host kernel.

Another solution would be to ship the necessary headers with qemu source:
host kernel might get changed without all programs being rebuilt.

That discussion is coming up every other month. I think the conclusion so far was that ppl don't want to include the kvm headers in qemu.

I'm personally all for it. That'd also make the luvally builds easier.

thanks, it now compiles fine on both ppc32 and ppc64.

I've encuntered two issues under my quick test with CRUX PPC 2.6
(32bit) as host. This was my start command:

$ qemu-system-ppc -m 256 -localtime -hda 25a_qcow.img -cdrom
crux-ppc-2.5a.iso -boot d

The apple32 boot kernel on that iso image is linux-2.6.29.4
 
1) with -M g3beige it boots fine but segfaults loading the system.
2) with -M mac99 it boots but seems to be unable to find a proper IDE
device.

No problems, instead, with qemu-system-x86_64 when i
tried to install a guest linux x86 os on my ppc32 host.

Please use gdb's backtrace feature to find out why/where it breaks.

Yeah, that's because your guest kernel doesn't have cmd64x support  
compiled in.

it's the same bootkernel as above with cmd64x module builtin therefore
it's an unexpected error.
