The man page of acpidump(8) says that "kern.allowkmem" must be set to
some value in order for the program to work properly. However it does
not define to what value it must be set. I am not certainly sure if
there are other options between 0 and 1 but if so the man page should be
fixed anyway with these options IMO.
Cheers,
Emil
