Actually, they had someone on the inside discouraging them. :-)

They adopted Linux as yet another OS for the S/390.
Let's see if they open up for other architectures as well.
But then again on the S/390 Linux runs as yet another guest OS under VM,
which makes the platform and VM more attractive, but it makes no sense
for AS/400 customers to run a Unix on their box, as they'd have bought an
RS/6000 if they had wanted to, so IBM probably isn't too excited about any
Unix porting efforts to the AS/400, just like you said.

It is on
as linked from http://www.linux.org/
The port is just in the planning state and for the old CISC AS/400 only, though.
I don't know if the AS/400 9402 E02 mentioned in the original post is
RISC or CISC, but I guess since the RISC AS/400 are PowerPC-based they might
be a slightly easier porting target than the OS/400-tailored CISC versions.
