Ah right. I don't suppose kldload -v shows anything useful about the
problem loading it? Ah, never mind, it may be obvious .. lightly
skimming your asl.y530.gz, I recalled folks having to patch something

Hopefully adding the LEN0068 to ibm_ids might allow acpi_ibm to load; if
not more digging may be needed for this model.

I'm assuming running 9.x? I didn't see uname output in this thread.
Strange; according to that PR this was supposed to have been MFC'd last
November, but didn't make it into 9.1-RELEASE sources. Committer cc'd.
