So I'd originally thought that the sony-acpid daemon simply wasn't pointed
at the right location however I've now updated to ubuntu 13.04 on my Vaio
VPCZ12CGX.  I used the new kernel module that Mario provided the link to
which compiled fine and after that I loaded up the daemon and all is
working.

I didn't like the fact that the brightness of the display was picked up by
the ALS and the color of the window that I had open would then adjust the
brightness of my display.  Anyway I changed the daemon source a bit so that
the display brightness only does what the user asks of it.  I mainly use
the daemon only to get my keyboard to do what I want.  I've included my
modified version of the daemon as an attachment to this email.
