No. Neither powerbutton nor lidbutton works with ec_initr=1.

Where do I find this? Do you mean interrupt 9 "IO-APIC-edge acpi" in
/proc/interrupts?
With ec_initr=1 I don't see that interrupt 9 increases.

With ec_initr=1 /proc/acpi/button/lid/LID0/state seems to work sane:
gps@medusa:~$ cat /proc/acpi/button/lid/LID0/state # lid opened
state: open
gps@medusa:~$ sleep 5 && cat /proc/acpi/button/lid/LID0/state # closing lid quicker than 5 seconds
state: closed
With ec_initr=0 (and acpid *stopped*) I see interrupt 9 increases.
