Old info.
In 2007 the European PS3 (and some 80GB model in US) already used the PS2 emulation to run almost all the PS2 software... there are even a compatibility list in the Sony site.
This the us games list (20GB/60GB = Hardware BC; 80GB = Software Emulation BC): http://us.playstation.com/support/compatiblestatus/index.htm
The 60 GB in Europe uses Software Emulation BC too.
