Ubuntu kernel patches

[Julien Poissonnier]

Is there a list of the patches applied to the ubuntu kernel ?
I'd like to apply the software suspend patches from 
http://softwaresuspend.berlios.de/ but they seem to need more or less 
the vanilla sources. However if I use a vanilla kernel, I won't have the 
Ubuntu patches, so I wonder what I'll miss... (lots of wlan drivers, 
what else ?)
Or is there another way to get software suspend 2 to work with the 
Ubuntu sources ?
