If we modify the linker script:

     _end2 = .;
     _end3 = ALIGN(4096);
     _end4 = ALIGN(PAGE_SIZE);
     . = ALIGN(PAGE_SIZE);
     _end = . ;
     PROVIDE32 (end = .);

and the result is:

00001000 A _end
c067f678 A _end2
c0680000 A _end3
c0680000 A _end4

Possibly some section with a zero vma is being placed before _end.
Generate a link map to see if this is so.

Playing with this further I think its related to the -me500 option we pass and thus wondering if its something with the APU section handling. If I hack the kernel up a little and pass -m440 instead things seem to be ok.
