Datapoint; With latest X201 BIOS (BIOS: 1.14 / ECP: 1.08/1.08) from lenovo I can get i915 driver working on the external display by removing the modeset and vesa elements from the kernel command line. I also get full effects etc. and i915 is in use according to lsmod. This is using 'stock' 64 bit 2.6.32-22 generic kernel. I cannot get any display on the LCD panel at all, although It will wake up the backlight if I try to switch on both screens.
This new BIOS has improved a few items - I understand that the ACPI is now more stable and certainly the display on the external (4x3) monitor 'fits' a lot better than it did before.

Not sure it's much use, but just in case....
