Tried to recompile the 3.0-wip kernel on the XO-1.75/os9 (only takes 2 hours :-) where among other things sound and usb was build as a module, and got:
Kernel: arch/arm/boot/zImage is ready
Building modules, stage 2.
MODPOST 308 modules
ERROR: "alc5631_spkr_mute" [sound/soc/mmp/snd-soc-olpc-xo-1-75.ko] undefined!
ERROR: "usb_disconnect" [drivers/usb/host/ehci-hcd.ko] undefined!
make: *** [__modpost] Error 1
make: *** [modules] Error 2
For the "usb_disconnect" appears to be a patch in newer kernels (I'll test it).
As far as I understand "alc5631_spkr_mute" was introduced as a solution to #11409 by John Nettleton.
I was wondering if this is related to the incompatible headers or with the patch itself.
If you could spare 2 minutes I would appreciate any pointers because 2 hours is a long time ;)
