My results on Intrepid...
I installed apw's kernel on an SL300 type 2738-53G running Intrepid, and it disabled brightness adjustment completely, both with keys and with the Gnome brightness applet.
empo@ubuntu:~$ cat /proc/acpi/video/VGA/LCDD/brightness <not supported>
The current Intrepid kernel has reversed brightness keys.
Going for lunch now...
