Kenton,

No, OGR does not support curves from the personal geodatabase.

For datasources where curves are supported for reading (Oracle, NTF, DGN)
they are converted to linestrings.  The GML driver does not support curves.

There are no short term plans to add curve support to the PGEO driver nor
to add general support for curve geometry types to OGR.

There is a (vague) long term plan to implement the "new" simple features
geometry types which I believe includes curved paths for linestrings and
polygons.

Best regards,
