	I don't know enough about the sound card modules to be able to suggest 
anything very useful, sorry :(. All that I CAN tell you is that no alsa 
modules are loaded on my machine and sound works perfectly, though I'm running 
Kubuntu 10.04 which doesn't use Pulseaudio by default... very early on I 
enabled the use of pulse. So maybe this is something to do with the Pulseaudio 
config and maybe deprecated ( for Ubuntu ) kernel modules rather than real 
hardware issues. Maybe if you could find the sound related modules that aren't 
loaded in 2.6.37 that were in 2.6.36 and I can see if they have just been 
removed from the default build?

	Now this is REALLY odd. The module stores the state in a static variable 
and simply returns stamina or speed based on that value, so at the very least 
if writing to the speed_stamina file changes the LED, it should read back 
correctly. Nothing has changed from Norbert's original in that respect.

	Well, the change is logical enough. However, as soon as one of the NVidia 
modules learns how to play nicely with the Intel one, this won't work because 
both VGA adaptors will always appear on the bus.

	I'm not 100% sure, but I think that this will just be 
/usr/lib/mesa/libGL.so from the libgl1-mesa-glx package. If you're using my 
upstart script it may just be that you need to run ldconfig ( thanks Rutger! ) 
after changing over from one card to the other. I've now modded my upstart 
script to do this. Otherwise, something like:

apt-get install --reinstall libgl1-mesa-glx

	may fix it.

Adam.
