Thanks for the hint.

However, this doesn't work: it again bumps into internal_error because 
there's no gdbarch method for fetching pseudo registers.  How would such 
a method look for a target that doesn't have a frame pointer?

Also, strangely enough, tm-irix3.h does define a place for FP in the 
registers array (at index 30).  So why doesn't it define FP_REGNUM 
accordingly?
