What's going to break, if vanilla kernel is used?

[Alexander Skwar]

Hello!

As suspend/resume doesn't work with the kernel shipped with
Dapper, I'd like to try using the suspend2 kernel patch from
<http://suspend2.net/>. But the patch cannot be applied cleanly
against the Ubuntu sources.

Because of that, I'd like to use a vanilla kernel. But the
Ubuntu patches are there for a reason, I'd suppose. Is this
reason documented somewhere? Or, put differently, what do the
Ubuntu patches add to the vanilla kernel and what's not going
to work anymore after using a vanilla kernel?

Thanks,

Alexander Skwar
