How can I get an installer with an option for Apple Partition Map with os9 driver installation option?
Some known options:
1. Connect the Mac that has the drive you want to format for OS 9 via FireWire Target Disk mode. Requires the target machine with the drive, and another machine to access OS X for you.
2. Simply use the command line version of disk utility instead, called "diskutil". There's an option you can pass to the program to install the OS 9 drivers. I think it was called "os9drivers"? You will have to look up the exact commands to use, though, I forgot how to use that tool, personally, but I know it can do the job for you.
3. Boot into OS 9 and format it from there, using the appropriate Unsupported Mac OS 9 installer for your machine.
The reason your OS X hides the option for you is because it thinks you can't boot into OS 9, so it hides the option from you. Which is why connecting your unsupported Mac via FireWire Target Disk Mode bypasses the problem, as well.
EDIT: For option 2, check out the thread linked by @joevt above. Specifically, check
this comment, which shows you an example on how to format it via command line with OS 9 drivers.
