The attached patch is possibly all you need in mkgmap to be able to
route across non-straight boundaries - it simply recognises nodes that
have been tagged with mkgmap:on-boundary=1. Note, that this is an
XML attribute on the node element not an OSM "tag" element. 

The splitter would have to add this tag to the last point in each way
that has been split at a tile boundary.

Completely untested but it could be worth experimenting with.
