This is a pre-Lenovo T42p and X identifies the graphics card as an
[AMD/ATI] RV350/M10 GL [Mobility FireGL T2] rev 128

So far I have not tried WITH_NEW_XORG=YES, beause AFAIR that would not
allow me to switch back to console after starting X11.

The last line in the Xorg.0.log of the failed session was
[mi] EQ overflowing. The server is probably stuck in an infinite loop.
so I might give WITH_NEW_XORG=YES a try.
