I have been quite wrong with that statement, yepp. xorg-evdev fetches
the whole device-information. So if a keyboard provides an affected
ABS_* bit, it'll break, too. My ancient hardware didn't use any of the
higher ABS bits, though.
I'm sorry for the troubles caused. ABS_MAX must be at most 0x3f. So
please, go ahead and revert the 3 mentioned patches.

Thanks
David
