Sorry for the delay; I was travelling.

I modified qemu to make the flash type configurable, so it is not a problem
for me. However, anyone using upstream qemu will see the problem. My qemu patch
adding the option to configure the flash type was rejected, so those affected
will have to wait for a proper qemu fix.

I would suggest to not make any changes in the kernel: The qemu problems should be
fixed in qemu. I only brought this up to raise awareness that there is a qemu related
problem, not to ask for a change in the Linux kernel.
