With the boot param you at least get an idea how many other sytems are 
affected.

If you run the linuxfirmwarekit, AFAIK there is a test: it extracts both FADTs 
and compares the 32 and 64 bit addresses in case both are not 0 and throws a 
warning it they differ.
If people see this and they have some mysterious problem, they should give 
this: acpi_root_table=rsdt boot param a try (after applying the patches) and 
report back.
