What about debug.acpi.disabled="bus"?
If it works with debug.acpi.disabled="bus" but not with
debug.acpi.disabled="children", that means it's AcpiGetType()
that's messing up something.
Probably `set debug.acpi.avoid' alone should also work, because
I have read through that code, it just uses testenv().  Will it be better  
if we can add `debug.acpi.avoidpath' env?

there's one piece of code that I overlooked; when debug.acpi.avoid
is set, it avoids running _INI and _STA methods, and namespaces list
above are never scanned according to files `dmesg.acpi1' and  
`dmesg.acpi2'
(which proves that my guess was wrong). Finding out which _INI or _STA
methods(there are 25 of them) is the problem is bit of a work, but if
you really don't mind the trouble of finding it out, you may want to  
start
with somewhere around here:

                Device (CRD0)
                {
                    Name (_ADR, 0x00010000)
                    Method (_INI, 0, NotSerialized)
                    {
                        SMI (0x95, 0x04)
                    }
                    Name (_S1D, 0x00)
                    Name (_S3D, 0x03)
                }
change this to

                Device (CRD0)
                {
                    Name (_ADR, 0x00010000)
                    Method (_INI, 0, NotSerialized)
                    {
                        // SMI (0x95, 0x04)
After this line and the similar line in `Device (CRD1)' block have been  
commented out, everything works fine.

                    }

                    Name (_S1D, 0x00)
                    Name (_S3D, 0x03)
                }
then compile it with iasl command, save it as /boot/acpi_dsdt.aml, add
    acpi_dsdt_load="YES"
in /boot/loader.conf and reboot.
