I have a new theory - do we need to enable some sort of suspend on halt for Intel chips? I see we do this for various cyrix chips, and I saw in a search that pentiums with MMX have "auto halt" and "low power on auto halt" options: http://www-student.informatik.uni-bonn.de:8001/~petera/lpp/ Do we enable these? I don't see any CPU_SUSP_HLT options in initcpu.c for Intel chips.
