I did get the "bad" test first, ie. didn't get fix, SD card inserted.
Then powered off, removed SD card and got the fixes. I could also
repeat the feat by swapping SD card in and out between shutdowns.

Using 2007.2, and not accessing SD.

The place I used is my balcony, which is generally not too good place.
However, since I didn't get any visible benefit in any area from using
the new kernel, I stopped testing for now.

I haven't seen any other readily available builds besides those
mwester's andy+wester builds, but hopefully others can test eg. them
