.. but if I remember correctly, this was fixed eventually.

Title:
  Samsung R525 brightness keys do not work

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  This is likely similar to Bug #295251, but seeing that that one is supposedly fixed, I'll open a new bug report.
  The brightness control on this laptop does not work (Fn+Up / Down) and produces e008 / e009 scancodes.
  Manually adding those through 

  sudo setkeycodes e008 225
  sudo setkeycodes e009 224

  triggers the appropriate action, but the release code is not generated. I thought this was fixed with an older
  kernel release, at least according to bug #295251 ...

  I am on Lucid, kernel 2.6.32-21-generic. Hardware is Samsung
  R525-EIkee.

  uname -a
  Linux hadburg 2.6.32-21-generic #32-Ubuntu SMP Fri Apr 16 08:09:38 UTC 2010 x86_64 GNU/Linux

  Will attach further logs later.
