Here's a quote from Stefan:


"I think we should be careful as
this easily breaks the code in very nasty places (especially SSE chooses
the registers for ROMCC, so this definitely breaks some boards)

"The settings have to be the most conservative, not the best possible.
That means if there is a single CPU for a socket that does not have SSE,
SSE has to be off for that socket. Choosing SSE to be on because there
is a single CPU for that socket that has SSE will break other systems."
