Port to AS/400

I've been reading about the suggested ports of NetBSD, or other
unix-like os to AS400.

http://www.netbsd.org/ports/#suggested-other

I've read the archive of the list and saw that this is a question that
have raised
several times during the past years with little answers.

Anyway, I noticed a break link since this page:
"http://users.snip.net/~gbooker/AS400/ibm.htm"
no longer works.

Anybody knows if there is an attempt to port NetBSD to RISC based AS400
like the 9402 with the 400-2131 model processor?

Thanks
