FYI, The latest code on the ACPICA branch spits out the physical address
for dynamic tables in dmesg and the latest acpidump can read it by
specifying a physical address as a parameter.

My view is that if we export any tables in sysfs, we should export them all,
including dynamically loaded tables. The current /proc/acpi/fadt,dsdt
is inconsistent.

I agree, that we can do this later.
