Is it powerpc or powerpc64? Just for completeness...

boot cd:,\ppc\bootinfo.txt

works for me with 9.0 rc3 powerpc64,

boot cd:,\boot\loader cd:0

works for me with older 9.0 powerpc snapshop...

Your error messages seems to be not related - first one points to some
trouble reading CD (I got the same when I pulled CD out and then tried
something), while the second one seems to show completelly other
problem - at least on my PowerMac there are just temperature and
voltage sensors, with fan control unit as well, hanging off iichb0.

So I would just try to test CD for reading errors in another box, or
maybe try to burn new one...
