I'm looking for a way to access raster layers in an Esri File-GeoDatabase without using ArcObjects or ArcPy, specifically I would like to access the raster layers with GDAL. I understand that the GDAL FileGDB and OpenFileGDB give access to vector datasets within File-GeoDatabases, and that ESRI's own FileGDB C++ API does not support raster access.
Is anyone out there aware of any open source solutions?
You're almost there. This is on Windows 7, Python 2.6.5 32bit, and GDAL 1.9.0:
>>> from osgeo import ogr
>>> driver = ogr.GetDriverByName("FileGDB")
>>> ds = driver.Open(r"C:\temp\buildings.gdb", 0)
>>> ds
<osgeo.ogr.DataSource; proxy of <Swig Object of type 'OGRDataSourceShadow *' at 0x02BB7038> >
>>> ds.GetLayer("buildings")
<osgeo.ogr.Layer; proxy of <Swig Object of type 'OGRLayerShadow *' at 0x02BB7050> >
>>> b = ds.GetLayer("buildings")
>>> sr = b.GetSpatialRef()
>>> sr
<osgeo.osr.SpatialReference; proxy of <Swig Object of type 'OSRSpatialReferenceShadow *' at 0x02BB7080> >
>>> sr.ExportToProj4()
'+proj=utm +zone=15 +ellps=GRS80 +towgs84=0,0,0,0,0,0,0 +units=m +no_defs '
>>>
Once you open the FGDB, then use GetLayer to get at your featureclass.
There is a solution, but you must have FME installed on the same machine as MapInfo. If you have FME installed, you can use the Open Universal Data option in MapInfo. It will allow you to open any of the formats that are supported by FME.
Note, in the last image, you'll notice that I have two options for File Geodatabase. The first is the API translator, the second is the ArcObjects translator which becomes available when ArcGIS is also installed on the same machine.
So, to answer your question, yes it is possible, but not unless you have FME.

I've just released a prototype program Arc Raster Rescue which extracts raster data from the ArcGIS File Geodatabase format.
