OK, let me know if you need any details from me when you get around to
looking at this. It doesn't seem to actually cause any problems.

Also, is there any way to force the DPI with nouveau? I'm specifying

 -dpi 96

... on the X command line, but I still see

 (**) NOUVEAU(0): DPI set to (129, 203)

... in the Xorg.0.log, and the font sizes are all weird in X. With the
nvidia binary driver I used to have to use

 Option DPI "96 x 96"

... in xorg.conf - is there something similar with nouveau?

I'm guessing its my laptop panel reporting incorrect values for
something, but I still need to work around it :)

Cheers,
