Thanks Yokota-san for tracking down the problem.

And if such a problem was found, please send ACPI data with the
report.  This is very useful info. for our debugging.
To get ACPI data, 
 # acpidump -o foo.dsdt > foo.asl
and send both files to acpi-jp@.  See also acpidump(8).

I personally, don't have enough time to hack the code for now (sorry),
but I think that newly added `placeholders' code causes the problem
for my first impression.

    for (i = 0; i < 100; i++) {
        rid = i;
        res = bus_alloc_resource(dev, SYS_RES_IOPORT, &rid, 0, ~0, 1, 0);
        rid = i;
        res = bus_alloc_resource(dev, SYS_RES_MEMORY, &rid, 0, ~0, 1, 0);
        rid = i;
        res = bus_alloc_resource(dev, SYS_RES_IRQ, &rid, 0, ~0, 1, 0);
    }

Mike, do you have any idea on this?

Anyway, Yokota-san thank you very much for finding a workaround.
