First of all, I'm now running the 2.6.12-rc6 kernel with your original
fn patch applied as you said. I still have the same problems...

I first thought the problem was caused by gnome, but after testing with
an X server running only xterm where the fn key also didn't work as
expected (actually, the fn key didn't work at all in the xterm), I'm
thinking it has to be something else that is causing the problem. I've
also tried booting the old kernel ( where I found the fn key
working as expected (same xkb setup). The fact that I experience the
correct behavior on the same software but on the older kernel also leads
me to think there is some difference in the kernel leading to the
strange behavior.

What is strange is that Fn+Down/Up works as expected *only* in
gnome-terminal when switching tabs with Ctrl+PgUp/PgDown. It does not
work in any other program I've tested.

If anyone could help me debug this, it would be very appreciated.

Thank you
