If I'm not mistaken, the function of bit 2 depends on the state of W mode rather than absolute vs relative mode. From page 40 of the PDF: "If the Wmode bit is not set (0), then Gesture is reported and bit 2 refers to DisGest. (..) When this bit is 1, the Relative mode mouse packet reports the true physical button states, and the Absolute mode packet’s Gesture bit always reports as zero." So it still has a meaning in absolute mode, when Wmode is disabled. I've tried the patch, it works, but I don't believe it's correct. Sorry for the reversed patch, I'm not really experienced with making patches.
