After a fair amount of testing, I have not experienced this problem on the current official Ubuntu beta AMI for Intrepid. This might be because Intrepid starts more slowly than the Hardy AMI I build (2min vs 40sec). It's possible that if an official Hardy AMI were released it would experience this problem. It's also possible that as more people use the Ubuntu kernel these AMIs will boot faster, so I still recommend tossing in the fix.
