Arraider,
I am no mechanic, but i recently built a 29" chiner. I figured with all the reading that i did that i would have to "fit" some things. I was right i recieved my frame and the bottom cup in the headset was a little tight and out of round. May bee .002 -.003". Careful sandpaper work and this was fixed. My other problem was like yours be it nowhere as severe, but all the same my brake bosses need a little truing, but the bolts in mine were strait enough. A few minutes with a file and they were fixed It did fustrate me though.
I think i may have a solution for you. If you use the 160 rotor and get rid of the spacer the shorter bolts wont conflict with the rotor,but u will need to file the brake bosses perpendicual to the rotor. Then bolt the brake caliper to the bosses with the avid cones on the top of the brake caliper,(between the caliper and the bolt head only). Hope this explanation is clear.
If it were me i would not try to re-drill and tap the bosses. This may work, but i don't think that there is enough working room in the stays to properly re-drill and tap new threads. Plus you would likely need a jig of some sort to ensure they were strait.
I believe that the vendor should be responsible for a manufacture defect period! That being said a simple fix may be easier than dealing with customs, vendor, shipping, travel and so forth.
I am confident i could make this repair, but no matter make sure before you try any thing you are confident as well. Because if you damage the frame the vendor will likely tell you that you are on your own.
Good luck. I hope the vendor steps up and takes care of this. Keep us posted.
