Are any Certificate Authorities using 4096 bit keys for their intermediate and root certificates?

I know you can, of course, use a 4096 bit key for your server certificate, but I usually see 2048 bit keys from the Certification Authorities, and wonder if any are using 4096 bit keys yet?

Thank you.

This is probably better suited on itsecurity, I don't see any question in here related to cryptography. This might sound strange to you, but to explain it with an analogy - a question about which companies sell chocolate cakes is off-topic on a baking forum. – orlp Oct 13 '13 at 4:15
You might be right. I thought about that shortly after posting, but still thought that users here might have a good knowledge of this. – user981178 Oct 14 '13 at 1:11
