If Win8 is as broken as we are I'm ok with the module option. It just sounded to me like right now we don't know of a way to make all machines somewhat happy, combined with the other pile of random backlight issues the assumption that we do something (maybe something a bit racy) that windows doesn't do isn't too far-fetched. So I'm not wary of the machines where the aml is busted for acpi_os=win8, but for the others where this broke stuff.
Windows 8 isn't broken because (as far as we can tell) the Intel drivers under Windows 8 never use the ACPI backlight set function. Of course, it would be nice to have that confirmed by Intel.
