Ok, if you have measured that method1 is faster than method2, let us go for

I believe method2 would be faster if you had a large out-of-order execution

This causes problems because it's a truly stupid device that does
not work properly at PCI [relative] address 0x. It simply
does not respond at that address.

This is the old DRM driver for radeon, which relies on userspace to

Actually, even the old DRM driver occasionally hangs on this machine,
I suspect a missing barrier, but I might be completely off base.
