i would guess that this change is the big problem:

+.section .rodata,"a"
 #include "syscall_table.S"
 
 syscall_table_size=(.-sys_call_table)

this is going to move sys_call_table to a different section, and the
check in osi_probe to see if the "found" sys_call_table is in the 
right section is going to fail.  while it is now marked readonly
i dont think the x86 platform can actually make it readonly.

i suspect the author of probe syscall will have a better idea
about possible fixes.

it also looks like it might be time to start using the keyring.
the ia64 does have a readonly sys_call_table that cannot be 
modified.
