I can confirm this behavior. To reproduce, I did:
* launch ec2 instance (ami-fa01f193 us-east-1
ubuntu-lucid-10.04-amd64-server-20110201.1)
* disable lucid-updates
* sudo apt-get update && sudo apt-get install mysql-server-5.1
* modify /etc/apparmor.d/usr.sbin.mysqld, adding hashes to the two lines below:
# /var/lib/mysql/ r,
# /var/lib/mysql/** rwk,
* enable -updates
* sudo apt-get update && sudo apt-get dist-upgrade
* system hangs on:
Setting up mysql-server-core-5.1 (5.1.41-3ubuntu12.9) ...
Setting up mysql-server-5.1 (5.1.41-3ubuntu12.9) ...
Installing new version of config file /etc/init/mysql.conf ...
These 4 processes are running:

libmysqlclient16 mysql-client-core-5.1 mysql-client-5.1 mysql-server-core-5.1

/var/lib/dpkg/info/mysql-server-5.1.postinst configure 5.1.41-3ubuntu12.7

because you commented out the lines in the config file, mysql cannot
access /var/lib/mysql. I suspect you have app armour messages in your
dmesg indicating this.
I'm not sure if I should call this bug invalid or confirmed.
