Funny, I also have a 'not too old, not too new' laptop as well. I also upgraded from Ubuntu 8.04 to 9.04 & the had sleep issues.
In fact, before the upgrade, the laptop would refuse to wake up from sleep. After the upgrade - it works just fine. The laptop is a Lenovo N200, by the way. I enjoyed your anecdote, i hope you enjoyed mine too.
