I hear that NIST Key Mgmt guideline (SP 800-57) suggests that the RSA key size equivalent to a 256 bit symmetric key is roughly 15360 bits. I haven't actually checked this reference, so I don't know how they got such a big number; caveat emptor.
I would imagine it'd be the result of fitting some reasonable exponential to both keylengths and extrapolating, which then of course blows up...for once *literally* exponentially. ;)
