No good thoughts, the driver is simply horrible...
You might be able to pick some interesting info by
running with tape->debug_level set to 4 (There is an option,
but I forget what. Just assign 4 to it after
a call to idetape_add_settings. Be prepared for a lots of
tracing.

If you come up with any patches, post them to the list.
