Oops. I misunderstood your problem. Could you test with
CONFIG_DEBUG_VIRTUAL?

After commit 9caf25f996e8, user for CMA memory should use to check
PageHighmem in order to get proper virtual address of the page. If
someone doesn't use it, it is possible to use wrong virtual address
and it then causes the use of wrong physical address.
CONFIG_DEBUG_VIRTUAL would catch this case.

If it doesn't help, is there a way to test n900 configuration in QEMU?

Thanks.
