Need to modify the Program Header info

Hello all,
I have a situation where the program headers built into an ELF executable
seem like they are incorrect. The target is an MPC5200, Here are the
program header and section header info:
Program Header:
LOAD off 0x00000000 vaddr 0x80000000 paddr 0x80000000 align 2**16
filesz 0x00009fc0 memsz 0x00009fc0 flags rwx
Sections:
Idx Name Size VMA LMA File off Algn
0 .text 00001f80 80008000 80008000 00008000 2**2
CONTENTS, ALLOC, LOAD, READONLY, CODE
1 .data 00000040 80009f80 80009f80 00009f80 2**2
CONTENTS, ALLOC, LOAD, DATA
2 .bss 00000000 80009fc0 80009fc0 00009fc0 2**0
ALLOC
3 .stab 0000219c 80009fc0 80009fc0 00009fc0 2**2
CONTENTS, READONLY, DEBUGGING
4 .comment 00000098 8000d838 8000d838 0000c15c 2**0
CONTENTS, READONLY
5 .stabstr 000016dc 8000c15c 8000c15c 0000c1f4 2**0
CONTENTS, READONLY, DEBUGGING
The Section header displays the correct load address, file offset and
Alignment information. The program header is incorrect. Does anyone know of
a way to modify the program header without messing around with the ld
script? I looked at objcopy and it seemed like it might do the trick but I
can't figure out what commands to use to change the program header
information.
Thanks for the help!!
