If your board is limited to recognise 1GB per slot, there's no way to get around that, no.
How have you determined this is the case, though? Often manuals and manufacturer's specs aren't updated and it's possible you can use 2GB sticks in the slots, but of course I wouldn't advise trying it blindly as it'd be a waste of money if it didn't work.
P.S. Welcome to the forums!
