I think neither of them will work up front.
BKK has written a cgminer driver for the Klondike (and I have provided minor input into that) but I've no idea what's actually going to happen there with the actual hardware.

Bitburner? We've never heard anything from them.
If it is a pure Avalon clone, it may work.
But I've also got nothing to do with Avalon at all (ckolivas has one) so I can't say what will happen there.
(He had to pay for his Avalon ... 50BTC ... and since then the Avalon performance has gone from ~70GH/s to ~80GH/s thanks to him ...)

The problem is that a lot of people seem to think we ask for hardware with an agenda to simply be given stuff for free.
(The whole Me vs GitSyncom drama should have made that clear - "proper support" is provided by ckolivas - many months after they said they would provide it but never did)

When Klondike finally appears and people release them, the basic board is like ... 15GH/s?
So yeah I'm really gonna make a fortune from that in a month or two
Next week I'll have 130GH/s courtesy of the company that a lot of people hate (I already have 70)
So it sorta puts the whole "You only want a Klondike for free" into the realms of ... why should I have people abuse me for that ...

I sold an Icarus for $1800 back in Apr coz I had 2, I kept the 2nd one coz I need it to support cgminer.
I will keep the 'tiny' devices mining probably long after they cost more to run than they generate coz it means I can easily test changes on the hardware "We Support"

Yes it peeves me also

... and I will add of course what most know but never hurts to remind people, MineForeman.com paid and posted my RPi to me.
Thanks again

... and sorry to derail the thread ... yeah this is how I sometimes start a war around here ... but I don't think it will this time
