We should check if the symbol is available for xserver compatiblity.
So below is updated patch for check this.
I'm fine with this patch sets and tested against sony bravia doesn't

Subject: [PATCH] introduce i830_hdmi_priv.has_hdmi_sink
HDMI is compatible with DVI, and we've seen many boards that
use HDMI port for DVI output.
So Zhenyu proposed this flag: i830_hdmi_priv.has_hdmi_sink
to indicate the presence of HDMI capable monitors.
