After updating to the latest BIOS 1.32 and Ubuntu 11.10 I can now successfully boot into Ubuntu without using acpi=off. I can even leave Optimus switched on in BIOS and Ubuntu seems to be using the Intel card when the nvidia driver is not installed. I'm booting with legacy BIOS mode (not UEFI), both virtualisation options turned on, Optimus turned on with OS detection turned off.
