Yes, the change of WORD to BYTE is not necessary with 10-CURRENT.

I don't understand ACPI well enough to answer your followup.  All I know
is that there is some change in the ACPI parsing behavior between
9-STABLE (which triggers AE_AML_BUFFER_LIMIT in the broken _SRS method)
and 10-CURRENT (which used to panic but after jhb's fixes now boots
correctly).  Could it be possible that _SRS is not being called at all
with the new ACPI code?
