xorg 6.8.0.1, i810 driver, i855gm and xinerama. Doesn't work

[d4rkst4r]

Dear xorg,
i've got a new laptop (sony vaio vgn x505vp) with an intel 855GM
chipset. I tryed to enable xinerama with the i810 driver but without
success.

I've tried with latest xorg 6.8.0.1 but at the best i can get only Clone mode.

In the Xorg.0.log i've noticed this:

(**) Option "Xinerama" "on"
(**) Xinerama: enabled

That would mean that the xinerama extension get loaded by xorg. But
taking a look further, i find:

              If you encounter this problem please add
                 Option "DisplayInfo" "FALSE"
              to the Device section of your XF86Config file.

Ok, but what's mean "Extended BIOS function 0x5f11 not supported."?

And why i can get xinerama work?

Thanx a lot to you all,
