Sven: I have executed the recommended procedure. I didn't appreciate the need for the remote login until you explained the purpose - sorry for the delay.

I have performed the following to create the attached file:
booted with "nouveau.modeset=0" and "drm.debug=0x04"
logged in remotely
executed "rmmod nouveau; modprobe nouveau modeset=1"
executed dmesg > dmesg.drm.modeset_1
gzipped the latter file
I noted where the rmmod etc. was executed in the file
(near line 643)
Attached the file to this note...
I'll try the 3.2.0-rc7 kernel you mentioned after this note goes.
