Little in that scrolling in terminals seems to work better. A failure
mode where the mouse cursor refuses to move seems to occur less often.

Yes, the hangcheck timer checks still fire intermittently and graphics
performance is still hit & miss. There is a failure mode that I call the
Amiga loading screen where vertical lines appear that are all a pixel
wide and are continuously changing in colour.

The AGP aperture is exactly 256MB in the location that the DRM warning
complained about, so what I did with the script was an attempt to answer
its lament. It accept that it may be completely meaningless in practice.

Regards,
Tony V.
