[Mactel-linux-users] Any problems caused by Apple firmware updates?

[<sj...@ut...>]

I've been thinking of updating the MacOS X part just for the fun of it. 
Being paranoid that I am, I was wondering if any of you had any issues 
with OSX (firmware) updates and Linux device drivers? I'm especially 
worried that iSight and/or Atheros wlan updates might break them in 
Linux. Which firmware files/dirs should I backup in OSX just in case 
something goes wrongs.

Thanks in advance,

Samuli
