Finally, I got the new TTM memory allocator code merged with OpenChrome DRM.  The code now compiles without syntax errors.  As expected, it could not boot the X Server the first time or the second time I tried it.  I am still working on getting it to work properly, and I expect this to take a week or two.  Code commit will probably not happen for 2 to 3 weeks.  Anyway, this is a huge step forward for OpenChrome Project, and my other future underserved graphics device revival projects.
