Did it. But what a pain, …
First I had to put the original DVD into a machine with X. There I had to make all invisible files visible with the terminal and the command:
defaults write com.apple.finder AppleShowAllFiles -boolean true;killall Finder
(reverse everything by replacing "true" with "false")
Subsequently I could see a file called "OS9General.dmg" inside a folder ".images". I could copy that image to a hard disc and mount it with 10.4.11. Subsequently I burned the content via Toast Titanium 6 as disc image to a CD. The CD was not bootable at the Powerbook Ti. So I created another disc image from that CD with Toast 5 Titanium at the Ti directly. Then I could bourn a bootable CD from that new disc image.
This new CD is booting the Ti. An installer is not available with this 9.2.2 but "Laufwerke konfigurieren " is working and all 430,6 MB (System Folder, Applications, Documents) can be dragged and dropped directly from CD to the HD, …
WTF!
I wanted to install Mac OS 9.2.2., and had to deal a whole night with a system, that I don´t need, don't like and will never use, just to bypass that system at my 9 notebook. Compared to my original 9.1 retail CD this mothing more than a piss take by Apple to all Mac users of that time. And remember this is the only original Mac OS 9 system for that 1 GHz Powerbook Titanium that Apple ever released, all other Mac OS 9.x do not work!
