A PS2 Linux kit costs 250 euros and is available on the web for anyone to
buy.
The cheapest PS2 Devkit costs 10000 euros and is only available to a
registered developer.
The former is simply the linux OS running on a standard ps2 and allows you
to program what you like within the confines of that OS, or by jumping
through a few hoops, allows lower level access to the machine. It comes with
full hardware manuals, minus the one for the sound chip. Developing anything
low level is likely to be a painful process involving a lot of reboots, and
debugging is very primitive. There are no real libraries to speak of other
than some kernel modules/devices for accessing the custom hardware, and
whatever is available from the community at large. There are a few fulltime
support staff, but most of the support comes from other users.
The latter is a ps2 with more memory hooked up to an internal PC host which
controls it, and allows more-or-less unintrusive control from a development
environment running on a networked PC. Low-level development is the norm as
the PS2 only has a thin native kernel and no OS to speak of. Debugging is
pretty advanced even with the "free" tools that are supplied by Sony. There
aren't a lot of libs worth speaking about on this setup either, but there is
a wealth of sample code and considerably more support staff dedicated to
helping you out.

Yes, it's a feasible approach, but I'm not aware of anyone having actually
done it. Actually, I believe there was at least one developer who prototyped
on a linux kit before moving to "real" development systems, but that was
mostly down to confusion over licensing issues, and delays in getting them
signed up.

At this time none of those work on PS2 linux, and it's doubtful they ever
will - the costs in porting would far outweigh any profit they might somehow
make. You're pretty much stuck with whats freely available - of course you
could get the source for a public 3d engine and port it...
