Vali is a great pick, very much in the style of the stuff you mentioned. It might be hard to find their album though, but maybe prophecy will release it again.
October falls is a must, tuoni and marras albums (also the new ep is in that style). Very much in the style of the above but without the vocals.
Neun welten also on prophecy, is another folk acoustic band you'd probably like them.
You might try Nest from Finland. They're also not exactly in the style you mentioned but their new album is very good.
There's this band from Finland who i wish i could find more info about. Band name is Eisefen. Apparently it may have one member from Tenhi in the group. They're very in the style of Tenhi's early stuff acoustics/flutes long dirgy songs . Awesome awesome stuff! Here's an mp3:

There's two russian bands that might be some interest. They have a bit more instrumentation (piano violins). One is called Neutral and the other is
Romowe Rikoito.
For some german stuff maybe some forseti, orplid, Werkraum. I especially like forseti, there's more vocals but rougher than say empyrium (Helm is such a huge positive for them vocal wise). Still these might be of interest.
There's also Stille Volk from France. Most of their albums are very traditional folk. They have a medieval type sound, some of their stuff is more upbeat though. EDIT: If you like this style, there's a few more bands i can recommend.
This band from France Fjallstorm, i think they're a metal band but they have one album of stuff in this style. Here's two mp3s, if you like i can send the whole album. Not sure where you can buy this.

IMWI is from Spain and they play a very traditional folk style. The whole album is available here:

For the past few years i've searched for bands in the same style as those albums you listed, and there's really not that much out there. That combines that style of acoustic playing with the vocals as ulver/empyrium
do.
