Comment 64 for bug 486154

A lot of the discussion in this bug has to do with metacity and pulse, but for people who don't use gnome, metacity, pulse or any of that stuff, and just want their pcspkr module to beep when asked under lucid, I just posted a blog article:

Basically, I had to un-blacklist it in two places, /etc/modprobe.d/blacklist.conf and by removing the obsolete /etc/modprobe.d/00local that some earlier ubuntu version had put there and upgrades never removed.
