It's 17 kb away from empty. Also, firmware.agent seems to complete
successfuly from what I can tell. Lee Revell suggested on alsa-devel
that I should try with 2.6.12 since there have been changes in the
driver model since 2.6.10 (what i'm using). Indeed that seems to have
been the cause of the problem. With 2.6.12 I was able to play audio
nicely.

However, with 2.6.12 both support for my video hardware (radeon mobility
m6 ly on a sharp mm20 laptop) and my wireless network (prism) is broken.
I guess I have the choice between being blind or deaf. :(
