Description of problem:
After installing F16's last kernel update my system no longer boots. Instead, the following is shown on screen:

Trying to allocate 1059 pages for VMLINUZ
Got pages at 0xd59d5000
[Linux-EFI, setup=0x10cc, size=0x422db0
_

From this point on nothing happens anymore, while the caps lock LED is blinking. The value for setup varies if booted with different kernel parameters. The system is a Thinkpad X220 (exakt model: 4290W1B, see attached lshw output) with BIOS compatibility module disabled. Fedora is installed on a GPT disk with EFI system partition and gets started from Grub legacy. Pretty much the standard Anaconda recommendation for UEFI systems.

With the 3.0 kernel from the initial installation the system starts fine. Naturally, there are no syslog entries from the failed boot attempts with the 3.1 kernel.

Version-Release number of selected component (if applicable):
$ rpm -q kernel
kernel-3.0.1-3.fc16.x86_64
kernel-3.1.0-0.rc3.git0.0.fc16.x86_64

How reproducible:
100 %

Steps to Reproduce:
1. Install 3.1 kernel from updates-testing repo
2. Reboot system
3. 
  
Actual results:
System hangs after hitting enter in Grub

Expected results:
System comes up like with previous 3.0 kernel
