It isn't very good...Lion is supposed to get an update but I can't run it...I have a 32-bit processor and Lion is 64-bit only. Xquartz gets updates every now and then...but I'm not optomistic for a fix for a while... In macports...I'll see if I can set that xinput2 configure option. Right now it looks like it isn't specified at all, on xinput. If without-xinput2 works, then I'll be a happy camper. I'll post back once I test it.
