Simon,

If you're willing to do a bit of work to actually prepare the patch
and test the results, I can walk you through pretty much exactly what
needs to change (basically you just need to remove one block of code
and change a #define).

Steven has been really busy with other stuff, so I don't think we
should count on his participation in this process.
