lenny iso signed with key 64E6EA7D

[Rob Owens <rowens@ptd.net>]

I downloaded the latest Lenny netinst for i386.  The SHA512SUMS file is
signed with a key id of 64E6EA7D.  However, I can't find any info on
that key anywhere.  I tried searching public keyservers and googling for
it, but nothing has turned up.

Call me paranoid, but I never install a system unless I can verify the
signature...

Can anybody shed some light on this?
