Can Epson Perfection 2580 scanner be used w/OS 10.8.2?

I used my Epson Perfection 2580 Scanner with my old Mac, which was an eMac. I've recently upgraded to an iMac running OS 10.8.2.

The Software Update function downloaded a driver update for the scanner, but when I click on the Scanner icon in Applications, it tells me that this OS no longer supports PowerPC applications.

Online forums talk about using Rosetta, but Rosetta isn't supported by Mac's new OS, etc., etc.

Bottom line: Does this mean I am unable to use this scanner with my new iMac? Does this mean I must march out and buy a new scanner?
