How was your 10.5.8 image created? What was it created on/from?
There has been no change to hardware on the Unibody machines since 10.6 came
out, so technically a 10.5 image should work fine. Usually a machine
doesn't become a "built for 10.6" machine until there has been a hardware
change, necessitating new boot loaders.
That said, you do want to make sure you are using a 10.5 DVD that came out
after the Unibody machines came out. I believe that would be 10.5.6 or
higher, but someone else may want to confirm that.

I had the same experience when I loaded Mac OS X 10.3 on a PowerBook that
came with 10.4. Most things may work, but the older OS does not have the
correct drivers for everything.

We built the image on a late 2008 iMac using 10.5.6 then applying the 10.5.8 Combo Update. This was the recommended way that Nick from Jamf had us do. The Backlight functionality works correctly on 2 other MacBook Pros (Early 2008 - non-unibody) that we have, as well as an old PowerBook.
Thanks,

Just to be certain, I took a Unibody I just received this week and loaded my
10.5.7 image on it and the keyboard back light works as expected: on in low
light, off in regular light.
My 10.5.7 image was built off of a DIB (drop in box) disc that was shipped
with a 17" Unibody MBP earlier this year, in July I believe.
So, just make sure you are using a disc from another Unibody and you should
be fine.

Don't the combo updates usually include the new kenel extensions and
drivers required? I've usually had good experience with using the
latest combo updates. However if you get a machine with 10.6 and
install 10.5 on it you may run across issues... I have not had
problems yet.
Ken,
Yes, the combos usually do include this. Apple did NOT include the drivers
from the first aluminum iMacs in the last build of Tiger though. That
wasn't the case though in Leopard from what I've heard. I don't think the
kb that Don posted actually applies here from a technical perspective in
this specific case. All bets are always off once they rev the hardware,
such as they did with the iMacs last month. I personally just got a new MBP
early this week and it has the same EFI rev as earlier this summer with
Leopard, so you should be able to get the backlight working properly. My
guess is that the combination of installing it on an iMac and then running
the combo just didn't place the drivers for the backlight correctly.
Whenever possible, we always use a macbook pro to make our OS images as they
have the most extra features that need to be supported such as the
backlight, and until recently when all touchpads became capable, support for
the extra gestures on the touchpad.
