Hi Sepherosa,
got some additional information (hope it helps).
After this hunk (from fbsd) the overrall system reaction is ok (say, like no loading of acpi.ko)

I tried booting a kernel with same debug level (events+function), but without the acpi code upgrade and i have an interrupt storm as well...
kernel bootlog with no acpi upgrade (i.e. acpi 20090521):
evsci-0154 [136] EvSciXruptHandler : ----Entry
evevent-0309 [136] EvFixedEventDetect : Fixed Event Block: Enable 00000120 Status 00000011
evgpe-0525 [136] EvGpeDetect : Read GPE Register at GPE08: Status=00, Enable=02
evsci-0175 [136] EvSciXruptHandler : ----Exit- 0 0
kernel bootlog with acpi upgrade:
evsci-0154 [136] EvSciXruptHandler : ----Entry
evevent-0297 [137] EvFixedEventDetect : ----Entry
evevent-0309 [137] EvFixedEventDetect : Fixed Event Block: Enable 00000120 Status 00000011

the GPE registers may be interpreted in a different way in the new acpi release, but GPE00 register is now seen...
