            Bug ID: 96397
           Summary: legacy modesetting removal breaks CLE266
           Product: xorg
           Version: unspecified
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/openchrome
          Assignee: openchrome-devel at lists.freedesktop.org
          Reporter: xavier at bachelot.org

The commit that removes legacy mode setting
(b48fb4176c96b04f5de8b2ee20f55af404ba0db7) breaks my CLE266 setup (1920x1080
monitor on VGA).

Current git master (0.4.169) is still broken for me.
My working setup is 0.4.0 plus a patch that reverts legacy mode setting removal
(attached).

Attached are the X logs and registers dumps for both the working and
non-working setup. My guess is the issue is with registers 6A, 6B and 6C.

I recovered a patch from my mailbox dating from the mode setting code rewrite
more than 3 years ago and before I reverted the CLE266 to use legacy
modesetting back then. It was fixing the CLE266 to work with new mode setting.
Attached too.
