After lots of hacking, I managed to get IKVM to run HelloWorld under mono. This involved lots of changes/bugfixes to IKVM, the mono runtime and the class libs. I intend to submit a big patch to the mono mailing list shortly with the changes.
Great news!
Unrelated to the above, I checked in a bunch of changes and updated the source and binary snapshots. I'll be out of the country for two weeks, so there probably won't be much activity.
