i only tested the gdal module proper, not the scripts. and yes, the only other
bit is a trivial UnsignedInt8 -> UInt8 near the end of gdalnumeric.py.
but, you are not going to get any speed gain WRT the current cvs. for real
zero-copy i had to patch some more files in non trivial and non backward
compatible way.
as soon as i have something reasonable i'll post it to the list.
cheers,
alessandro
