Thanks Scott. It didn't occur to me to try switching my instance to small,
do the install, and then switch back to micro. I'll give that a try.
Also, for some reason I thought the amd64 builds of Ubuntu were lacking in
some components. Maybe that's only true for client, but I definitely saw a
recommendation somewhere to use i386 unless there was a real need for 4GB
of memory.

The workaround is only useful when you're setting up a new instance.
It's useless for the instance I already invested a day setting up. It
would be a really good idea to put a warning somewhere in the docs for
micro instances. Once AWS starts handing out free micro instances by the
thousands, the urgency of this bug will increase dramatically.
Well, you actually can apply the work around to an existing instance. If
the instance is hung, you should be able to stop it (/sbin/halt). The
start it in a m1.small , 'apt-get -f install', then stop again, and
restart into t1.micro.
Additionally, its only an issue with i386 instances, and t1.micro can be
either amd64 or i386. amd64 are generally more useful as you have higher
powered options than you do with i386.
I'm not trying to discount the severity of the bug. It is a real kernel
bug that is exposed by java, and could also be exposed by another
application.

t1.micro instance hangs when installing sun java

Bug description:
Binary package hint: cloud-init
I booted the 32bit EBS lucid AMI (ami-1234de7b) for a t1.micro instance. I
attempted to install Sun Java. The instance hung during the install. Repros
every time. Only repros on t1.micro instances. I tried adding swap in case
it was an out-of-memory condition, and it still repro'd. No reboots or
anything else like that were involved so it's not the same issue as #634102
