I've never used a horizontal scroll wheel -- what are the common uses for it? Why should the acceleration be separate for the two directions rather than using the same factor? Why does the kernel need to emulate this rather than having user-space implement the emulation? (If the answers to the last two questions justify putting this feature in the kernel, my only suggestions on the patch are style-related: scroll_accel{x,y} should probably be spelled scroll_accel_{x,y}, and there are missing spaces around the / operator when calculating stepx and stepy.)
