Make sure that you've implemented the smartport calls -- the prodos MLI is not used at all. It really threw me for a loop initially, but fortunately the smartport service routine does virtually the same thing for block reads/writes so it might not be too heavy of a burden to support. The Jace implementation is zero-firmware, so I'm afraid I can't be much help in providing a 6502-based smartport handler or anything. If you're taking a similar zero-firmware approach though, you might want to peek at how I abstracted the smartport calls in case it is of any use to you (pointer arithmetic, PC and stack manipulation, etc)
Abstracted smartport driver: http://java-ace.svn.sourceforge.net/viewvc/java-ace/jace/src/jace/hardware/SmartportDriver.java?revision=241&content-type=text%2Fplain
Mass Storage implementation (the Smartport MLI glue is at the very end of the file): http://java-ace.svn.sourceforge.net/viewvc/java-ace/jace/src/jace/hardware/massStorage/CardMassStorage.java?revision=268&content-type=text%2Fplain
