Reload the page, it got supported a few hours before you ask the question :)

You need to install -current or 2.0, built after 2004/06/22. Catch an 
auto-build on http://releng.netbsd.org as soon as it gets available, 
or, if you are impatient, cross-build the system yourself from another
machine (NetBSD can be easily built for any platform from various Unix
systems, Linux included).

In order to create a bootable CD-ROM, create a tree with the snapshot, 
and at the root put ofwboot.xcf and the netbsd-INSTALL kernel. Make an
ISO and you'll be able to install.

Yes, I fixed that a few days ago. The interrupt controller was not
enabled, thus making keyboard, mouse, disk, CDROM and network unable to 
read anything. It works well now.

Sure. For now it's a new land to discover, and I'd like to fix all the problems
before NetBSD-2.0 gets released.
