any reason why only suse has this, but not mainline ?

i came across that module in suse kernel just some days ago and asked novell ( https://bugzilla.novell.com/show_bug.cgi?id=396132 ) , but they don`t have any objections.
chris mason didn`t reply on direct request....

so, if it`s useful, who is reponsible for pushing it upstream ?

Nobody is. That is why it isn't. Feel free to do the work.

It would need some cleanup before submission. e.g. the ooops/panic etc. options
are fairly useless and should be removed and there needs to be more documentation.
