For any modern Linux and Windows, CHS simply doesn't matter.

What I don't get is that how picking up a custom geometry can make things work when there is *no* reliable way to determine which geometry was used during partitioning once the partitioning is complete. Most BIOSs these days will simply report the geometry as being 255/63 regardless of the geometry used during partitioning. So, how can using a custom geometry give that nice "just works" for x86 boxes when nobody knows what geometry is in use?
