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seems that the 'Ben' -series PPC kernel tree is no longer maintained...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:
-----------------------------------------------------------------------
dylan@surf:~/notes$ webcam webcam.conf
reading config file: webcam.conf
ioctl: VIDIOCSCHAN(0,Composite,flags=0x0,type=2,norm=3): Invalid argument
ioctl: VIDIOCMCAPTURE(0,fmt=4,size=48x32): Invalid argument
video4linux webcam v1.3 - (c) 1998-2001 Gerd Knorr
grabber config:
size 640x480 [16 bit YUV 4:2:2 (packed)]
input composite, norm ntsc, jpeg quality 85
rotate=0, top=0, left=0, bottom=480, right=640
write config:
local transfer /home/httpd/uploading.jpg => /home/httpd/cam.jpg
"food? 2005-01-16 19:08:17"
-----------------------------------------------------------------------
here is a sample image generated by webcam (no video signal, so it is a black
screen...)

here is some information from the 8500, with planb module:
