Alright.  Knowing nothing about the inner workings of X, I can at least 
look through the two log files (in my previous post) and see where they 
suddenly go in very different directions.

Using the numbers down the left-hand side of the logs (I don't know what 
they actually are, but they seem to be ascending, so I will use them as 
markers), at 32.959 in the Wheezy log and at 2271.289 in the Jessie log 
they both say:

     (++) using VT number 7

a few lines below that, in the Wheezy log:


[    32.974] (II) Module fbdevhw: vendor="X.Org Foundation"
[    32.974]    compiled for 1.12.4, module version = 0.0.2

and in the Jessie log:

[  2271.291]    compiled for 1.16.4, module version = 0.0.2

[  2271.291] (**) FBDEV(0):  Built-in mode "current"
[  2271.291] (==) FBDEV(0): DPI set to (96, 96)


In Wheezy, the graphics card seems to have been found and a depth of 
24bpp is being used by RADEON(0) with a GB of graphics memory, while in 
Jessie, Screen 0 is getting deleted and the radeon module is removed.  
Instead of RADEON(0) we see FBDEV(0), instead of 24bbp, only 16bbp is 
being used.  Only 1536kB of video memory is being used and the screen 
size is set to "Virtual size is 1024x768 (pitch 1024)".

I don't know enough to determine what is causing these differences, let 
alone how to correct the problem.  If someone else can figure out a 
solution I would be most grateful.

Marc
