> - a backup (no exported sql or dump file) of the old MySQL 5.0 installation
First, we need to understand how you got the backup. It sounds like you have a copy of the disk files? Was mysqld stopped when you copied the files?

Plan A: (I do not know if it will work):
Install 5.5, but do not start.
Copy all the files _except_ the "mysql" directory (`mysql` database)
Start mysqld.

Plan B:
Get a copy of 5.0; install it.
Do mysqldump of everything but the `mysql` database.
Find out the logins you need to reconstruct. Do SHOW GRANTS... if necessary.
Remove 5.0 executables and data.
Install 5.5
mysql <dumpfile.sql
