After disabling dpms, I again experienced the slowness issue
similar to #682816.
After leaving the box with a locked display, I type my password, unlock
the X session and find that almost everything (especially the text
displayed inside XTerm windows) is repainted extremely slowly.
If I close all the graphical applications and try to exit from the X
session (which was started with startx), I never get back to the
console. Hence I cannot login again and the only way out is to press
the power button to shut the system down (luckily the power button
press event is handled and triggers a clean shutdown...).

After doing this, I found the attached snippet
inside /var/log/kern.log: it's really similar to what I obtained with
dpms on, although not identical.

Maybe #714531 and #682816 are two sides of the same coin?
