Not a pain at all.

Ok, the easiest way at the command line to do this is likely with pico
(although you should think about learning vi or emacs). To change the
yaboot.conf file you would do the following:
pico /etc/yaboot.conf
Then change the line mentioned in the previous email. Make sure to save
before quitting. Pico is pretty simple to use and there is help built in
if you get totally lost, so you should be ok.
afterwards you can do this:
/usr/sbin/ybin
but you have to be the user 'root' to do so. This will write the the PRAM
pointing the boot-device to your bootloader.

Yes, I know that, but you don't want to reset it, you want it to contain
info about where your bootloader is. MacOS X and YDL both change a
parameter named 'boot-device' and you need it to be pointing to your
bootloader patition (this is what ybin does, and what the Apple Startup
disk does). Holding down the option key at bootup makes the machine ignore
that parameter and look for bootable partitions.
