Here's the list from everymac.com of the last Macs that can run Classic:  http://www.everymac.com/articles/q&a/macos-9-classic-support/faq/last-macs-to-support-macos-9-classic.html

Some Powermac G5s and iMac G5s are indeed on the list.  And yes, everymac.com says that Classic requires OS 10.4.11 or earlier -- it can't run on these computers in 10.5 or later.
