Unfortunately I missed the replies but I debugged this problem further and the Problem is that GenFw set's the alignment based on "sh_addralign" in the Elf header.
The 'common-page-size' flag doesn't change the value of this field though. what it does change is the Alignment value of the Program Headers: Program Headers: Type Offset VirtAddr PhysAddr FileSiz MemSiz Flg Align LOAD 0x010000 0x00000000 0x00000000 0x042f8 0x042f8 R E 0x10000 LOAD 0x0142f8 0x000142f8 0x000142f8 0x000d4 0x000f4 RW 0x10000 GNU_STACK 0x000000 0x00000000 0x00000000 0x00000 0x00000 RWE 0x10 the section alignment still stays at 0/1/4.
