Anyway, the proof of the pudding is in the eating. Can you point me to a secure site that uses a key size >1024 bits? I can't find one for love nor money.
This root certificate was found in the binary code for Netscape 7
Data: Version: 3 (0x2) Serial Number: 1 (0x1) Signature Algorithm: sha1WithRSAEncryption Issuer: C=US, O=America Online Inc., CN=America Online Root Certification Authority 2 Validity Not Before: May 28 06:00:00 2002 GMT Not After : Sep 29 14:08:00 2037 GMT Subject: C=US, O=America Online Inc., CN=America Online Root Certification Authority 2 Subject Public Key Info: Public Key Algorithm: rsaEncryption RSA Public Key: (4096 bit) ========== Modulus (4096 bit): 00:cc:41:45:1d:e9:3d:4d:10:f6:8c:b1:41:c9:e0: 5e:cb:0d:b7:bf:47:73:d3:f0:55:4d:dd:c6:0c:fa: b1:66:05:6a:cd:78:b4:dc:02:db:4e:81:f3:d7:a7: ... ===
There used to be a 16384 bit root certificate in Netscape 6 but I see it has been removed. It belonged to Thawte.

grep Modulus foombar | sort | uniq -c
1 Modulus (1000 bit): 38 Modulus (1024 bit): 26 Modulus (2048 bit): 2 Modulus (4096 bit):
So, slightly less than half the commercial roots have moved to 2048 bits and several have moved to 4096. These are the numbers for the old Netscape 6:
1 Modulus (1000 bit): 54 Modulus (1024 bit): 1 Modulus (16384 bit): 34 Modulus (2048 bit): 1 Modulus (4096 bit):
This should give you a pretty good snapshot of what the people who can pay Netscape $250,000 dollars a shot to have their roots included are doing...
