Pulling in fix for bug #140713 for Gutsy release

Due to real mode usage in gfxboot, Ubuntu has never been able to install 
     under KVM or Xen on Intel (VT) processors.  The latest version of 
gfxboot attempted to fix this problem but there is a bug.

A one-line fix is available that fixes the problem and allows Gutsy to 
be installed under KVM or Xen.  The fix came from the gfxboot maintainer 
(Steffen Winterfeldt) and has gotten a lot of review on kvm-devel.

While it is rather late to apply such a fix, the reward is great 
(allowing Gutsy to be used for open virtualization on Intel) and the 
risk is low since the patch has gotten a lot of review and is pretty 

I've included the patch in this email but the bug report should be 
consulted for more information around the patch.

Sorry if this is the wrong place for such a request, I'm not that 
familiar with how things work in Ubuntu.  The bug hasn't gotten much 
attention on launchpad and it's very important this is taken before the 
release of Gutsy (or it won't be useful until Gutsy+1).
