	Expanding on "September ... I think":
	Try September 26 as a reference date.  Sometime close to then I
a) updated world+kernel to the latest version of current, so also b)
updated to the latest drm-current-kmod and gpu-firmware.
	Question: is there a way for the less sophisticated user <waves>
to tell whether the cause is in the drm knod or the firmware kmod?


			Hope this helps,
