I imagine the PCIe bus is a big advantage as it won't have suffered the
same code rot that AGP has. I don't get the impression that Linux
support for AGP was ever totally working. The HD 6570 has good support
in 'radeon' which has been improved even recently. Linux supports this
generation of GPUs far better than any other OS.

I've got a PCI ATI GPU somewhere around; I might try that and see if
the problems go away. If they do it will confirm the issue as specific
to AGP cards.

I've since installed a new SSD (Kingston A400) and I was able to
install MacOS followed by Debian. Both show in the OF boot picker and
the system automatically boots into Debian. I'm not sure why the boot
picker option was lost previously. Probably the interference by MacOS,
or a flat PRAM battery.

I'll wait for these fixes to land and for the Ports repo to be updated.
I'll try and remember to check back in a few months time, hopefully the
changes will have propagated by then.

I've just tried again, this time using mwm instead of MATE. Performance
is certainly better with this minimal window manager. Xterm is
responsive and usable. GTK apps are not perfect but are better than
with MATE. It would seem that Xorg simply suffers poor performance when
using 'radeon'. When using a lightweight wm this is simply less
noticeable, though performance is still better using software rendering.
