Sorry for the late response. I have not tested since 3.2, and it fail
booting almost right after 3.2....
It take me some time to be able to boot 3.9-rc1. I'll send the patch
in another mail.

The image of 3.9-rc1+the patches boots fine but with one warning which
is not seen without the patches:
NR_IRQS:16 nr_irqs:96 96
