A little more info:
When I removed the debug code, console sleep started
failing again (as it does even with older kernels). X11 sleep still
works. It seems like the problem is in aty128_sleep_notifier because
this debug code you suggested:

allows console sleep to work (not completely of course because the
screen doesn't shut off).
