@Montblanc: I think that's what happened to me. I didn't check the
debugging output so I wasn't aware of any segmentation fault but I know
that I was booting by default into a black screen, and I had to but into
one of the back-up kernels that grub keeps handy and run ppa-purge.

Title:
  fglrx-installer not working with HD2000-4000 "legacy" cards in Quantal

Status in Release Notes for Ubuntu:
  New
Status in “fglrx-installer” package in Ubuntu:
  Confirmed

Bug description:
  Following the AMD decision to change to a new driver support model for
  Radeon™ HD 4000, HD 3000 and HD 2000 series cards as per
  http://support.amd.com/us/gpudownload/linux/legacy/Pages/legacy-
  radeon_linux.aspx , fglrx-installer installs non-working drivers.

  I suggest the addition of an fglrx-legacy package to install the AMD
  legacy drivers for users with older cards or patch the current code
  base for use with these cards.

  Output for fglrx 9.00 [1]:
  # lspci|grep VGA

  WORKAROUND: sudo add-apt-repository ppa:makson96/fglrx && sudo apt-get
  update && sudo apt-get -y upgrade && sudo apt-get -y install fglrx-
  legacy

  This workaround will downgrade X to 1.12 and install the AMD legacy
  fglrx 8.97 (Catalyst 12.6).
