That's not really a reason to drop s2ram support. There are good reasons, 
without starting any old discussion again, to use s2ram instead of 99video. 

If you don't have s2ram (which you obviously do), you have no trouble. And for 
the rest, which want to use s2ram, they should report it to the s2ram 
maintainers. But this isn't your problem at all. You make it only complicated 
for all these users. They have to revert your patch ....

That all is easy to say if you don't use s2ram. And not everyone is doing what 
you do.
