  1002:7942 Please blacklist ATI XPRESS 1250 from Kernel mode-setting

Status in “linux” package in Ubuntu:

Bug description:
  Please add ATI Technologies Inc Radeon Xpress 1250 [1002:7942] to the
  kernel drm KMS blacklist.

  Testing has shown that KMS support for the ati xpress 1250 is inadequate, often resulting in a regression where the system hangs during boot up. Testers have found that booting with radeon.modeset=0 restores the system functionality. This is why this particular video card should be blacklisted.

  As suggested by Brice Harrington in bug #542208, comment 17, it is
  better to keep one report per chip.

  [initial bug report: symptoms of what happens when one tries to boot with kms enabled]
  Here are some details of what happens:
    1. setting nomodeset option
    2. editing boot option, removing quiet and splash
    3. Selecting Try Ubuntu
    4. System begins to boot, lots of messages are printed on the screen
    5. After 2-3 seconds, screen goes black although disk activity continues
    6. Screen keeps being black and the computer is unusable
