No, there won´t be errors when compiling as a module. Only when
actually loading the module.

I will look into this eventually.

I developped the driver with version 2.6.27-rc6-davinci1-05187-g91c2c53.

The breakage I see when I run the aplay utility is this:
  aplay: pcm_write:1394: write error: Input/output error

davinci-git version is the latest as of january 14
