I got it working as follows (remembering that I am on a 64-bit Lenovo T61): 1. Download the winetricks script. 2. EDIT the script to change $WINE from -wine to -wine32. 3. Run winetricks: sh winetricks (in my case, I made it executable and ran it direct). 4. Select vcrun2005, which downloads and registers the missing dlls. 5. run "wine32 regedit", navigate to HKEY_CURRENT_USER\Software\Google\SketchUp7\GLConfig\Display, and change HW_OK to 1.
