The paper I linked to seemed to suggest that they weren't using async IO in 9.2 -- which is fairly old. I'm not sure why the authors didn't test 10g.
There have been async io type parameters in Oracle's init.ora files from (at least) 8i (disk_async_io=true IIRC) - on Solaris anyway. Whether this enabled real or simulated async io is probably a good question - I recall during testing turning it off and seeing kio()? or similar type calls become write()/read() in truss oupout.
