No kidding.  The 68010's stack frame format for all exceptions is
different from the 68000's.  This means there is an extra word between
the stack pointer and the arguments to a GEMDOS, BIOS, or XBIOS call
made from Super mode.  It is possible to write code which deals with
this situation, and in fact it's been done here by way of prototyping,
but at this point it isn't planned for TOS 1.4.
