2.4-2.5 GB is the highest you will be able to get with OTM until it is certified to work as a 64-bit application.

I did run a test using the 5.5 OAS install, changed the JDK to Jrockit's 64-bit and was able to get the heap size to 6GB (on a 8GB machine) successfully. The sun 64-bit JDK was unstable. All of this is non-supported and will not work with the DASH license as well.
