I tested again with kernel 3.2.0-23.36 from Ubuntu 12.04, this bug is *still* present, the kernel does not send lid close events.
As per the last comment, I looked at what acpid says when I close the lid, it says nothing, so it doesn't even register the event because the kernel sends nothing.
My kernel version:
Linux snowflake 3.2.0-23-generic #36-Ubuntu SMP Tue Apr 10 20:39:51 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux

I'll return this bug to Triaged.
