success!
after getting X to run locally I fired up xawtv without any options and saw pictures. Grabbed a few frames for posterity and made myself a cup of tea.
The details
8600 ppc 350ev
320meg ram
Matrox Millenium 1 video card
Apple conference camera
kernel 2.4.19 (via apt-get) - compiled with planb and video for linux
xawtv version 3.7.2 - I did use the old (version 1.0) xawrc from the planb website
Thanks to dylan for the pointers for webcam, thats next ;)

Has anyone managed to get the planb driver to work (or better yet, with
the v4l stuff)? If so, how? What kernel, what distro, what phase of the
moon?
Yes. I have a working planb setup on an 8500/250 604e machine, running a custom compiled "2.4.23-pre5-ben0" kernel.
I am no at the machine right now, but i can forward some email
conversations that i have had about a year ago concerning the project.
Hi Dylan
I would very much appreciate any information you have on this project when you can spare a moment or two :)
thanks in advance

Well it has been a while since I have messed around with all of this... and it seems that the 'Ben' -series PPC kernel tree is no longer maintained...
I am not sure if the Bitkepper PPC kernel tree, or the official tree have code that is working... check here: http://www.ppckernel.org/tree.php?id=5 for the bitkeeper PPC kernel
also... I don't have the source code that I used to compile this kernel! i thought that I did somewhere... but it is not on this machine anymore...
I will try to get the planb driver working with a more modern kernel and report back here when i have some spare time. also -- i am pretty sure that the planb driver needs the i2c subsystem in order to function.
I have used the program 'webcam' to capture images from the video input hardware. here is some configuration information:
-----------------------------------------------------------------------
[grab]
device = /dev/video0
text = "food? %Y-%m-%d %H:%M:%S"
width = 640
height = 480
delay = 60
input = composite
norm = ntsc
rotate = 0
top = 0
left = 0
bottom = -1
right = -1
quality = 85
trigger = 0
once = 0
-----------------------------------------------------------------------
i usually run webcam like this:
webcam webcam.conf
here is some sample output:
-----------------------------------------------------------------------

here is a sample image generated by webcam (no video signal, so it is a black screen...)
