You could create a temporary swapfile when launching yum and delete it afterwards.

Openly said, based on my experience with my i586, I don't buy this. Usually, the memory requirements introduced other applications are magnitudes above that of yum. However I am not sufficiently familiar with OPLC to be able to further comment on this.
