ISTR reading not so long ago about active Xorg devs running out of working
65545 hardware to test with, and it may be necessary to stick with an older
distro and Xorg version to get it to work, or equip some devs with hardware
matching yours if you can't do the necessary driver dev work yourself. Try
looking through the list's archive if no one else replies with better info.
