This guide wasn't helpful. "modprobe nouveau" outputs nothing and
there is no nouveau module in the output of "lsmod." But nouveau
appears in the output of "lspci -vv."

Kernel: Linux-libre 3.2.4;
Xorg: 1:7.5+8+squeeze1.
I don't know how to check the versions of libdrm and nouveau DRM. And
I have no idea which ones are compatible.
Someone told me that I could check it this way:
$ grep DRICreatePCIBusID /usr/lib/xorg/modules/extensions/libdri*
Here is the output:
Binary file /usr/lib/xorg/modules/extensions/libdri.so matches
I don't know how to reinstall the whole system quickly or how to
install it harmlessly for the main system. (Could you provide a guide
on this?) It took me a lot of time to setup the current system.
And I don't really want to install Debain. [a]
Let's try to fix it in gNewSense. (My version is based on Squeeze.)
I'd also tried to ask gNewSense guys. [b]
