Kernel sound drivers are all from the ALSA project nowadays. Look into the
ALSA PC speaker driver, it is one of the simplest. More sophisticated sound
devices require you to use DMA. Read a book about Linux kernel driver
development before trying something with that. Note that the PPC
architecture and especially embedded boards are not in the focus of too
much people, so only PPC/embedded gurus amongst the kernel developers may
help you in some cases.

There has to be a framebuffer driver for the board you use to get this
working. Which board/development kit do you use?
