I think it's pretty clear that the KSE folks are ultimately responsible for making sure that the work gets done. On the other hand, it's also clear that writing the MD glue is an order of magnitude harder for someone unfamiliar with the architecture. The KSE folks have done 95% of the work already, so they deserve some assistance here. There's no need to treat a request for help as an imposition. FWIW, the same is true of libthr, which, last I checked, still doesn't work on Alpha. libc_r is being phased out, and without it, Alpha has no threading implementation. Marcel has a point here; it's hard to say that FreeBSD supports a platform if nobody is willing and able to keep it up to date. And it isn't as though there's a whole lot of work involved. Either one of libthr or libkse would be perfectly adequate, but someone needs to do it, or at the very least offer to explain how to do it. I have nothing against Alpha and I'm not trying to be critical of it, but someone needs to step up to the plate.
