Yes. Success.
I was able to successfully migrate solr 3.4 w/ solr-2155 solrconfig.xml
and schema.xml; but I had to rebuild the database (solr index data
folder).
<fieldType name="geohash_rpt"
class="solr.SpatialRecursivePrefixTreeFieldType"
geo="true" distErrPct="0" maxLevels="12" units="degrees"
prefixTree="geohash"/>
Everything seems to be working.
I need to try and see if I can convert the old 3.4 database... but when
we upgrade, we always rebuild our solr index.

You're supposed to add geo point data in "latitude, longitude" format,
although some other variations work. Is your updating process supplying
a geohash instead? If so you could write a simple Solr
UpdateRequestProcessor to convert it to the expected format. But that
doesn't help the fact that apparently you're index already has a geohash
for the stored field value.
Are all your fields either stored fields or aren't but are copied from a
stored field? It would then be an option to dump all data via CSV (take
care for multi-value fields) then load it into an empty instance.
You could "optimize" your index, which upgrades as a side-effect.
FYI there's a Lucene "IndexUpgrader" you can use at the command line:
http://lucene.apache.org/core/4_1_0/core/org/apache/lucene/index/IndexUp
grader.html
But again, if your stored field values are geohashes when you want a
lat,lon then this isn't going to fix that.
