Can TwinXMS 2048-3500LLPRO mix with other RAM?

As the title says.

What happens if I put a kit of Corsair 3500LL Pro in first two dimm slots
and
Corsair 4400 Pro in the last two dimm slots?
or
Mushkin RedlineXP (DDR500) in the last two dimm slots?

I know Mushkin RedlineXP is In CE-5/6, so would they mix with
Corsair 3500LL Pro, which is In BE-5?

Would they be compatible?

oh wise beards of Corsair, do you not know the
answer for mine question about compatibility if
I mix thou RAM with another?
