This is a good workaround.

We recently corrected a linker defect in the handling of VMA and LMA 
offsets.

The following snippet of documentation explains what happens to those 
sections *after* an AT> section, which don't themselves define AT>

http://sourceware.org/binutils/docs-2.19/ld/Output-Section-LMA.html#Output-Section-LMA
~~~
If neither AT nor AT> is specified for an allocatable section, the 
linker will set the LMA such that the difference between VMA and LMA 
for the section is the same as the preceding output section in the 
same region. If there is no preceding output section or the section is 
not allocatable, the linker will set the LMA equal to the VMA. See 
Output Section Region.
~~~

So, you must use "> ram AT > ram" to get VMA == LMA for the subsequent 
sections (or at least the next section).

Cheers,
Carlos.
