Relying to myself :) It seems like I found the problem. If I try to run the new qemu from inside scratchbox I get this:
[sbox-DIABLO_ARMEL: ~] > /scratchbox/devkits/cputransp/bin/qemu-arm-0.10
/scratchbox/devkits/cputransp/bin/qemu-arm-0.10: /scratchbox/host_shared/lib/libc.so.6: version `GLIBC_2.4' not found (required by /scratchbox/devkits/cputransp/bin/qemu-arm-0.10)
/scratchbox/devkits/cputransp/bin/qemu-arm-0.10: /scratchbox/host_shared/lib/libc.so.6: version `GLIBC_2.8' not found (required by /scratchbox/devkits/cputransp/bin/qemu-arm-0.10)
/scratchbox/devkits/cputransp/bin/qemu-arm-0.10: /scratchbox/host_shared/lib/libc.so.6: version `GLIBC_2.3.4' not found (required by /scratchbox/devkits/cputransp/bin/qemu-arm-0.10)

So it seems that the problem is the compilation of qemu on the host. Because of this qemu has dependencies to different versions of libc6. Versions that are not available from inside scratchbox. I'll try to fix that...

Cheers!
