It has always had a FPU. For a while, Mot was not advertising it because they had not verified that it worked properly, but it is an advertised feature now. It has always worked.

I don't have 8241/8245 experience, but I do have 8260 experience (also uses
the 603e core). Floating point (FPU) works well under linux.

Does 8260 really have full FPU support ?. I think it only has FPU register set and it supports
FPU load and store instructions, but NOT arithmetic instructions. Am I right ?

The story is much more interesting than that :-) You need to find someone at Motorola that is willing to tell it.
