at least currently they still ship a compatibility mode. With Ubuntu 64bit a colleague of mine experienced that it did indeed boot by EFI, and installed an appropriate grub for EFI, but the Lenovo firmware did not look in the right places. (It was probably only tested with the Windows bootloader.) With Ubuntu 32bit everything worked. Why? Because it did not contain an (U)EFI bootloader on the CD, and hence grub-pc was installed. Compatibility booting then worked as expected. (There was also quite a bit of pain involved in trying to get grub-pc working with amd64. It seems the BIOS still tried to do UEFI boots, possibly due to GPT being used by the Ubuntu installer, again due to EFI startup.) And note that the BIOS did not have much options, especially no option to turn off EFI booting. The machine in question was an Ideapad. Please include a boot menu option to force the installer to forget everything it knows about EFI despite booting successfully from it, so that you can still use BIOS compatibility (which is to many, IIRC even Linus Torvalds, still the lesser of the two evils of x86 booting).
