[Voyage-linux] kernel questions

[Punky Tse]

Hi Christian and Renier,

Just let me know what exact kernel config to turn on and I will enable 
in the next kernel.

Voyage kernel is minimized kernel with reduced modules.  This is 
historical reason to save spaces on a 128MB CF card, but this reason no 
longer valid.

I was surprised that why debian (wheezy) stock kernel won't work for 
you.  Perhaps you could try the backport kernels:
https://packages.debian.org/search?suite=wheezy-backports&searchon=names&keywords=linux-image

And Christian, thank you for the APU led driver.  But what are the 
differences between Christian's and the one posted by Jordi Ferrer Plana?

Cause building additional module was PITA for me. But as you succeed as well, in worst case you can use voyage kernel + your I2C.
