Is the older version of Mesa (7.10) the reason for missing 3D acceleration ?
From here (http://nouveau.freedesktop.org/wiki/MesaDrivers) I would think
that I need at least Mesa 7.11
nv50 and nvc0
On February 28th, 2011, the original nv50 Gallium3D driver was completely
replaced (in git) by the nvc0 Gallium3D driver ported to NV50 family of
cards. These drivers are included in Mesa 7.11. For nvc0 and the new nv50
drivers, you have to use at least the 2.6.38 kernel or you will encounter
memory corruption.
IIRC Aptosid had Mesa 7.11
