Ok, nevermind then, I misread things in the brief browsing I did of 
CHANGES.txt in the ACPICA distribution.  Do you have any ideas why an older 
version of ACPICA would accept his FACS, but the more recent versions are now 
choking on it?  Did the in-kernel version not verify checksums on FACS until 
recently?  It seems that acpidump has always reported that the table is 
corrupt, even with the older ACPICA distribution.
