strange:  fn key stopped working for me entirely.
i can't figure out what caused this change.  my
/etc/modprobe.d/options still says:
  options usbhid quirks=0x05ac:0x0230:0x00024800
i haven't changed that.
i suspect perhaps some change that's come down through
software update.

is anyone else seeing this?  running hardy heron with
gnome and all the software updates installed.

Status in Mactel Support: In Progress
Status in Source Package "linux-meta" in Ubuntu: Confirmed

Bug description:
hardware:  macbook pro generation 4,1 (feb 2008)
problem:  fn key not detected
test:  run xev.  press fn key.  nothing happens.
consequences:  home/end/pgup/pgdown don't work.

i was able to fix this issue by compiling my own kernel.
i downloaded linux-source from ubuntu hardy
(VERSION = 2,PATCHLEVEL = 6,SUBLEVEL = 24,EXTRAVERSION = .3)

and revised this file:
 drivers/hid/usbhid/hid-quirks.c 

used lsusb to grab the id of the internal keyboard device:
  Bus 005 Device 003: ID 05ac:0230 Apple Computer, Inc.

and revised the c file accordingly:

/* next line commented out by eitan and replaced with line below;
  changing address for device from 0x021b to 0x0230 which is what lsusb tells me
  my internal keyboard device id actually is
#define USB_DEVICE_ID_APPLE_GEYSER4_ISO 0x021b
 */
#define USB_DEVICE_ID_APPLE_GEYSER4_ISO 0x0230

rebooting with the new kernel, the fn key now works.
i don't know if this breaks other versions of the macbook pro
and am otherwise ignorant of the linux kernel source code.

thanks,
