this seems the best idea at the moment. only one problem. i really
dont know ia64 assembly. i managed to write a little function that
just returns and patching the syscall entry with that doesnt crash.
that's about the extent of my ability. i would guess that when
module functions are called from the kernel that a small stub
routine that preserves the kernel's gp and sets up the function's gp
is called first? perhaps i could look at this code for some help?
or if someone on this list would be kind enough...
