In the next few days to weeks. I'm nearly done with the IIvx kernel and I'll
put out an alpha kernel for that in the next couple of days.

The IIsi is almost the same type of video. Just a little tweaking should be
necessary to get that to work too, I just haven't gotten to it yet :)

Basic answer: Real soon now.

Thanks for your patience!
