I try to bisect ,but there are so many commit which will build fail,so I just get a good commit on master:

Comment 6 Wang Zhenyu 2008-10-08 00:43:24 UTC
Fixed in master:

commit 74571363539426abeb0a1af11f3bb545d91ed6c2
Author: Zhenyu Wang <zhenyu.z.wang@intel.com>
Date:   Wed Oct 8 15:36:10 2008 +0800

    Put forware VBIOS data parsing
    
    i830_bios_init() is called too late after output init, which
    makes bios data mostly useless, and caused all TV init fail as
    tv_present flag is not set.
