(1.22 iirc) available from Lenovo.
Upgrading the BIOS actually helped!
I followed the instructions to create a USB Stick found here: http://www.floccinaucinihilipilification.net/blog/2011/10/2/updating-the-bios-of-a-thinkpad-x220-using-linux.html
The suspend key (Fn-F4) still does not work, but that's a minor issue compared to not being able to suspend at all.
Be aware that you have to use EFI to boot Fedora. The latest firmware
revisions (at least, don't know about the former versions) make bogus
assumptions that you never want to boot from a GPT-partitioned disk while
using BIOS compatibility mode. It just won't try booting from a GPT disk, you
have to use UEFI.
I'm having grub-efi installed, which makes a good job.
