Maybe. But it's more more likely that we'll get SoftFPU to run first;
see below.

Executor does not currently support extensions such as INITs (which
are pieces of code that run when a Mac is booted up) or CDEVs (which
are Control Panel Devices). That means the software FPU can't work
under Executor. This will be true for Executor 2, also.
Getting some INITs and CDEVs working will be a high priority after
Executor 2 ships. The work isn't that hard, per-se, but the
compatibility issues are tricky since INITs and CDEVs often do stuff
that requires a greater degree of low-level compatibility than a
typical application does.
