[Xen-devel] ATI/AMD VGA passthru report

I'm trying to run AMD VGA passthru on latest XEN unstable with latest kernel.
I already have working setup with ancient xen-devel 4.2 and 2.6.32.x xenified 
kernel. See attached log.

So I tried just to update and patch xen and kernel, but I had no luck so far.

Xen has ati_vbios_patch_respin.txt sent to xen-devel by Wei Huang recently.

I tried two kernels 
testing-3.5-with-extra and xen/next-3.2 from
Both with ioperm opcode patch which is required by the ATI patch. See 

The xen/next-3.2 branch kernel was able to start booting windows.
With Catalyst driver installed I just saw bluescreen during Windows boot.
Without Catalyst driver Windows were able to boot but Windows ended frozen or 
USB was not working. It was hard to tell because input devices had no response 
at all.

The testing-3.5-with-extra (reported as 3.4.0-rc4) just crashed dom0 kernel 
during Windows boot. I guess I have to rework the io_bitmap patch somehow.
