Yes, they work great... got two of them today (from Woot's woot-off last week/end) and have both of them loaded up and in my N800, working wonderfully!
The read/write speed doesn't seem as good as the better ones i have but i'm not noticing any problem watching movies or tv shows from them.
You don't have to patch the kernel either because they're not SDHC, just regular SD.
thanks
