acpidump: RSDT entry 3 is corrupt

[meg...@r53sound.com]

I'm seeing "acpidump: RSDT entry 3 is corrupt" in my boot messages
on 6.3/amd64. The motherboard is an ASUS P5Q Pro Turbo with a Q6600.
 
IIRC, there's a way to extract the table so someone clueful can come-up
with a workaround for ASUS's failure to comply with the standard?
