Hello Xorg List,
Hello Thomas Dickey,
I still have the same problems with intel driver and a rotated screen.
The symptoms are:
I do something in the xterm like opening an e-mail in mutt or
type 'dmesg' and the screen freezes until I press a button or
wait several seconds, than the xterm immediately updates the
screen (the program has long finished producing the output.).
I type a command and the output is partially displayed:

I wait 10 seconds or press any key on my keyboard (like shift) or move
the mouse:

I can reproduce the problem on a notebook with another intel graphic
card.
I tried to take the x from debian backports, same problem, I tried to
recompile xterm, same problem. So I'm not sure if this a problem of
xterm or the xserver or the combination of the above. To show you the
problem I took two screenshots:

Xorg log of the second notebook I have trouble on:
http://upload.glanzmann.de/lifebook.xorg.0.log
Is there any parameter that I can try to tune, is there a patch for
xterm which I could try? I don't know if it happens in other applications in
acroread and google chrome (the two applications I run other than xterm
most of the time) I did not notice anything. However that could be
because I constantly move the mouse, when surfing the web.
Cheers,
Thomas
