I don't know what you really mean by "implementing ACPI" here. Certain
queries may generate SMM traps, but I haven't seen any event driven code
paths that do[1]. If you're polling hardware you may generate some
latency, but I don't think that's any great surprise.
It would be interesting to have a test case under Linux so we could
attempt to figure out whether it's an actual problem, or just Windows
doing awkward things.
[1] outside sort of obvious stuff like ripping out a hotswap bay and
/potentially/ critical battery status to switch on a warning light, but
if you hit those situations you're probably pretty much dead anyway
