crash spot = softice tries to get cr3 value from EPROCESS struct.
Only thing that comes to my mind is that internal structures might be changed.
Can you at least provide us with disassembly of ntoskrnl.exe!PsGetCurrentProcess , I just wanna be sure that internal structs haven't changed.

WinXP: ntoskrnl.exe!PsGetCurrentProcess
Code:
mov eax, fs:[124]
mov eax, [eax+44]
ret
Win2003: ntoskrnl.exe!PsGetCurrentProcess
Code:
mov eax, fs:[124]
mov eax, [eax+38]
ret
So the internals structures have changed, but it is still interesting that SoftICE loads on one PC running Win2003 without executing the code at all while the other PC crashes becuase of the changed structure.
