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

Now /proc/acpi/dsdt is present! However:

I also tried acpidump (thanks for the suggestion), which gave me:
<>
test acpidump # ./acpidump -t DSDT -o dsdt.hex
Wrong checksum for generic table!
