Hmm, I wonder why this is reserved, but renaming all instances of _T_0
to e.g. _TX0 or whatever should solve this?
Looks like a minor bug in the ACPI disassembler for me.

Remove the "*".
Could you explain why your DSDT is broken and what kind of bug you like
to fix.
To workaround ACPICA or DSDT bugs by simply overriding it is not a good
idea
as others might also slip into this. If possible, let's better try to
find a
general solution in the kernel/ACPICA code...
You also might want to open a bug report for your problem:
