Comment (by MaksimS):

 Another GETTILEIMAGE quirk that may be related to Zac's observations:

 There's a common problem with Autodesk MapGuide Enteprise 2008 and
 Autodesk Raster provider. Happens most often if there're several layers
 within base layer group, or a base layer displying heavy raster imagery.
 During base layer tiling operation it happens that some tiles simply get
 "skipped", and stay that way (cached as "empty" tile) even after MapGuide
 service gets restarted. Tiles get skipped (rendered empty) in a random
 fashion, no errors reported whatsoever.

 Testing platform:
 - Windows Server 2003 / IIS6
 - Autodesk MapGuide Enterprise 2008

 I hope Autodesk will get this fixed in 2009 version.
