Just to address the issue with the error you are getting Ed, Gamma Ramp is a function used to set the intensity levels of r/g/b . Looking at the source files, in wine this is handled via wine/dlls/x11drv/xvidmode.c . If ramp[0] >= 1 it causes this failure, I think, maybe this will work, if we bypass it by forcing that value to be 0. This will mess up the color intensity levels of course, but it might be a way to find out where the other problems are.
