Reading the changes of 2.8.0:  "quirk LVDS on ibase MB890 855GM board", by Zhenyu Wang. The IB890 is very similar to MB890. Reading from the xorg log file, it seems to me that the LVDS is attached to pipe B, but pipe B is turned off for some unknown reason.

Does this happen with KMS too? we have checked with acpi lib object for
LVDS detection, doesn't work this machine?
