Yes I do. 

Its in my personal library source and isn't yet in the main tree: yet
another thing on my list of 'things to do'. What kind of PKCS#8:
encrypted or unencrypted? It is possible to use some operation with the
new openssl asn1parse tool options to retrieve an unencrypted RSA key
from one in unencrypted PKCS#8 format.

If it is encrypted then the format is usually PKCS#5 v1.5, if its PKCS#5
v2.0 (unlikely but possible I suppose) it will take a bit more work.

If you have a sample private key you don't mind sending me I'll see if
my code can handle it.

Steve.
