It looks like it's a 2003 model (according to LowEndMac the 2004 had a 167MHz bus): http://lowendmac.com/imacs/emac-2003-800-mhz-1-ghz.html This should be able to boot 9.2.2 natively. But be careful, because according to the Apple OS Compatibility chart if the model is "eMac (ATI Graphics) - CD-ROM and Combo Drive" it will only boot the disk that was shipped with the system and not a retail disk: http://support.apple.com/kb/HT1835 Eric S.
