The last two Macs I purchased had OS 9 and OS X pre-installed, and booted into OS X by default. I don't know the secret magic key sequence to boot into OS 9, so I never booted into it.
But, here is the catch, the older ones (early G4's) only know to look for
Holding down the Option key causes Open Firmware to scan the device chains for bootable devices. Depending upon your configuration, "a few seconds" can equal 2-3 minutes... especially if you have twelve 9-gig scsi drives attached to a G3!
However, the purpose behind the "startup disk" control panel is to avoid this problem, especially if you are booting from something other "0,0". It sets the default "boot-device" environmental variable in the nvram. ("nvram -p" if you want to see what's there.)
As for multiple system folders in one partition, while they can co-exist, there can only be one "blessed" folder per partition. ... and once again, the issue of "blessed folders" has become an issue. Apple, just last week" issued instructions for how to bless a folder after a system restore has been done, thereby making the disk bootable.
If you are talking about OS X and OS9 in the same partition, the Option key has always seen the two. For a while, it was the only way to switch Rhapsody back and forth reliably.
[I vaguely remember that "Open Firmware" = "New World", but I'm not positive.]
