The pad driver does not interact with any hardware directly. What other
audio driver is on your system?
To confirm, try booting a kernel without the pad driver enabled -- you
should still hear the pop.

Ah,
This tweak:
$ diff GENERIC POP
1074,1075c1074,1075
< hdaudio* at pci? dev ? function ? # High Definition Audio
< hdafg* at hdaudiobus?
---
> ##hdaudio* at pci? dev ? function ? # High Definition Audio

got rid of the pop.

...and will also disable your speaker, I'd think.
Anyway, I assume we should try to figure out why the hdaudio
initialization pops?
