the nssearch patch certainly bypasses the first level problem. Here's
the dmesg output with that patch applied.

I also tried acpidump (thanks for the suggestion), which gave me:

You can dump your ACPI tables with acpidump, no matter if you
are booted in ACPI mode or not. Get the latest from pmtools here:

Any suggestions?
Replace the non-ascii character with an ascii one.
There is a patch about to work around this -- let me find it...
