You are referring the fact that 521 is not the power of base 2?
Looks like this is valid nevertheless.

% ssh-keygen -t ecdsa -b 512
Invalid ECDSA key length - valid lengths are 256, 384 or 521 bits
% ssh-keygen -t ecdsa -b 521
Generating public/private ecdsa key pair.
[...]

Wikipedia adds a note about this as well:

main(a){char*c=/*    Schoene Gruesse                         */"B?IJj;MEH"
"CX:;",b;for(a/*    Chris           get my mail address:    */=0;b=c[a++];)
putchar(b-1/(/*               gcc -o sig sig.c && ./sig    */b/42*2-3)*42);}
