Then please CC bugzilla-daemon at freedesktop.org - mails will be automatically
appended to bugreport.

Nouveau detects only 16 MB of VRAM. Can you verify it by looking at the card?
According to http://www.nvidia.com/page/geforce2go.html there were 16, 32
and 64 MB versions of GeForce2 Go.

Very similar bug was reported few months ago:
http://lists.freedesktop.org/archives/nouveau/2011-July/008631.html

Can you test patch (hack) posted there?

Note: that's almost half of your VRAM.
