Kernels with r269580 will panic when loading the radeonkms driver in

I seem to be able to load radeonkms just fine after r269580:
It's possible that it is related to actually using it, rather than
loading the module. I was only testing them together. I'm using vt and
the panic (page fault in kernel mode) occurs when TTM tries to set
memory attributes on some page while starting X. Before the panic, I see
all the normal Radeon module messages as you do, so the module seems to
have actually loaded correctly. The KMS console also seems to be
functional enough to display the panic message, so I suspect it's X that
triggers it.

Please try the attached patch, it seems to solve the panic for me. It
also includes a fix for Intel i915 gem, which I'm not able to test
because I don't have the hardware.
Roger.
Works for me on radeon. Thanks!
