Bug description:
  Hi

  I'd like to run kvm -kernel <kernel file> -hda <UEC image> -append
  "/proc/cmdline stuff" but this fails badly with both the EC2 and
  Virtual kernels.

  With the files from:
  http://uec-images.ubuntu.com/lucid/current/unpacked/

  Trying to run:
  kvm -kernel lucid-server-uec-amd64-vmlinuz-ec2 -hda lucid-server-uec-amd64.img -curses -append "root=/dev/sda"
  or:
  kvm -kernel lucid-server-uec-amd64-vmlinuz-virtual -hda lucid-server-uec-amd64.img -curses -append "root=/dev/sda"

  Fails awfully.

  I tried all combinations of nomodeset, vga=none, modeset=0,
  vga.nomodeset, vga.modeset=0, vga=ask and what not, but all failed.

  During the early kernel init, the VGA adapter emulated by kvm switches to graphics mode after:
  [...]
  [    1.073901] EXT3-fs: mounted filesystem with ordered data mode.              
  [    1.074640] VFS: Mounted root (ext3 filesystem) readonly on device 8:0.      
  [    1.075983] devtmpfs: mounted                                                
  [    1.076955] Freeing unused kernel memory: 796k freed                         
  [    1.093995] Write protecting the kernel read-only data: 7788k                

  I just get "640 x 480 Graphic mode" filling my whole remote terminal,
  and can't interact with the curses vm anymore.

  the -ec2 kernels in particular give some spectacularly corrupted
  output.

  Thanks,
