I am not sure that DNS lookups cause delays:
1. In Apache log files there are no host names, only IP addresses
2. Delays are observed only for HTTPS protocol and there are no delays for
HTTP (svn checkout of an empty project for HTTPS ~30 seconds and for HTTP ~2
seconds)

HTTPS handshake is also unlikely to cause the delays:
1. Ethereal Network Analyzed shows that port opened by Subversion client is
always the same for all the requests
2. I have configured SSLSessionCache and tested that it works with
openssl.exe
