It is appearing that lirc_gpio is broken for kernel 2.6.22. Two symbols are
missing from the bttv driver. In my searches, they appeared to previously
be generated by drivers/media/video/bt8xx/bttv-if.c.
WARNING: "bttv_get_gpio_queue" [/tmp/buildd/linux-
Could a kernel hacker who wrote the gpio driver speak to these at all? For
the moment, i'm going to disable them in the Ubuntu builds.
