I've put a (hopefully) recent acpidump source here:
ftp.suse.com/pub/people/trenn/acpidump
Should get available in an hour or so.

I expect you see:
"Dynamic OEM Table Load"
message(s) in dmesg and the SSDT which includes the ACPI parts which are
causing this is loaded at runtime. Older acpidump versions were not able
to extract these, the one I put on my ftp account should be able to.

Can you run it and put the output somewhere (related Ubuntu bug?) and
provide a pointer to it, please.
Hm, you could create a bug here:
http://acpica.org/bugzilla
It looks like ACPI code in the _CST function is triggering an ACPICA
interpreter memory bug when it tries to evaluate the func (guessing...).
