Hi Mike,

Just to be sure nv doesn't support exa with this card did you try
being explicit about it? I have an NVIDIA_NVS_3100M and thought
for the longest time I was in the boat of needing nouveau or changes
to nv but the following xorg.conf got me past the slowness (in 5.6):
Section "Device"
Identifier "NVIDIA_NVS_3100M"
Driver "nv"
Option "AccelMethod" "EXA"
Option "MigrationHeuristic" "greedy"
EndSection
it works! it is a bit faster now... still quite slow but it starts to be
in the "usable" range... it feels like my ThinkPad 600 pentium 166Mhz
with NeoMagic :)
But at least I can write this mail.
I see this in the Xorg log now, not very reassuring:

Especially the last WW which is memory related.
