By hand :) and using version control makes it easier.

Use first principal. Apply patch whatever hunks are rejected, apply them 
manually and then make the changes.

It would take less time than to hunt for tool that would do it right.

I had a patch, 12K lines long that came out of ancient cousin of CVS, some 80 
odd files patched. After some sed/cut and patch, I patched about 1200 lines by 
hand. Only took couple of hours or so.

I don't know how big and bad your patch is but IME no tool handle oddball 
situation in sufficiently good manner and more importantly correctly.

Or you could try patching the old version against which the patch was built 
and do a forward merge with release. It should be simple enough and should get 
out of most of the problems except conflicts.
