Sure; see below.

Ah, so GDAL supports them but Mapserver does not? Fair enough.
I did try gdal_translate to make TIFFs, but it wasn't writing
georeferencing info into the header. In fact, the gdalinfo from the
TIFFs was identical to that of the PAKs, and gdaltindex wouldn't touch
them because they weren't georefed.
