Dillon claims to have fixed it in vm_contig v1.3 and 
MFC'ed to vm_page.c 1.147.2.9:

  Makes contigalloc[1]() create the vm_map / underlying wired pages in
  the kernel map and object in a manner that contigfree() is actually
  able to free.  Previously contigfree() freed up the KVA space but
  could not unwire & free the underlying VM pages due to mismatched
  pageability between the map entry and the VM pages.


So yes, I think its fixed.
