Yeah, the doc will appears in a few hours when the web site is regenerated.

The windows binary should be available in the tomorrow nightly builds of Tamas 
: http://vbkto.dyndns.org/sdk/ (the -developement packages, revision >= 
r21548)

As far as Linux is concerned, like for the PGeo driver, we are constrainted by 
the MDBTools library that provides the MDB ODBC driver, but it has been 
unmaintained for many years and I find it to be quite buggy (especially when it 
fetches 'big' geometry binary blobs ).

To solve this, I'm currently working on a (not yet commited) OGR driver that 
relies on the Jackcess Java library ( http://jackcess.sourceforge.net/ ) 
through JNI invocation to read MDB databases. It works quite well. Should be 
ready soon hopefully.
