lost yaboot, open firmware fix?

[fudo]

I got Ubuntu successfully loaded on my Powerbook, and then I had some
unrelated issues with OSX. During the course of straightening that out,
I zapped the PRAM, and now yaboot doesn't come up at startup. And the
option key doesn't present me with any options, even though I have two
instances of OSX on separate partitions on the drive, as well as Ubuntu.
ISTR that it worked fine when I had OSX and OS9 on it, but it don't work
now. So, I'm guessing I need to do some messing around in Open Firmware
to get yaboot working again, which frankly, makes me a little nervous,
so any feedback appreciated.

The Ubuntu partition manager says my partition table looks like this:

1 32.2kb Apple
2 8.9MB HFS+ external boot
3 10.0GB Apple_UFS (OS10.3.4)
134.2MB Free space
5 9.9GB HFS+ Apple (OS10.3.5, current default boot partition)
6 8.9MB HFS+ external boot
7 1.0MB boot untitled
8 9.4GB ext3 untitled
9 442.2MB swap

From what I've gathered, I should type the following in Open Firmware:

setenv boot-device hd:7,\\yaboot boot

Comments?

setenv boot-device hd:7,\\yaboot boot

If you want to test that this is correct before saving it to OF, do

boot hd:7,\\yaboot

(I'm not clear on what that last ''boot'' is supposed to do.) That'll
try to boot a yaboot in the root of hd:7.

If I understand it correctly, it'll set hd7 as the default boot
partition. But, I'm just guessin'.
