Ok, so this code sets SSW FC2 bit and then reruns faulted data access 
and CPU uses SSW FC mode to access the faulted data? Is this documented 
somewhere? I didn't find anything about CPU supporting modification of 
SSW FC bits.

Current data fault restart part of emulation does not use modified SSW 
FC which probably explains the problem. Hopefully emulating this 
properly does not get too nasty... Other bits should be already emulated.

btw, what is the actual faulted instruction?
