2.6 is allegedly the stable kernel series, so if swsusp is the more
stable code base at this point, my vote would be to keep swsusp and
remove pmdisk from the kernel.  If someone wants to maintain a
separate BK-tree that contains pmdisk renamed to swsusp and fix all
the bugs, that's great.  On the other hand, there are a group of
people of are busy doing something very similar with swsusp2, and that
effort seems to have a fair number of people working on the patch and
testing it.  

So if we can somehow go from *three* idependent software suspend
implementations implementations to something less than three, and
increase the testing and effort devoting to remaining software suspend
code bases, this would be a good thing.

Pavel, what do you think of the swsusp2 patch, BTW?  My biggest
complaint about it is that since it's maintained outside of the
kernel, it's constantly behind about 0.75 revisions behind the latest
2.6 release.  The feature set of swsusp2, if they can ever get it
completely bugfree(tm) is certainly impressive.
