Armin,

once I saw the kernel was not booting on real device I wondered about
gcc and did a build for qemuarm/arm926js.
This one was booting fine on qemu.

I then beated OE's qemu to run for my spitz device (spitz is supported
by qemu but lacks some variables needed by the script) and with my
surprise it was booting...

So no, qemu is not a valid testbench for this specific issue :)

Cheers
Andrea
