May I ask you where you got this information from? I was grep-ing
around in the kernel source tree but I couldn't figure out that this
old.lstat is syscall #40, let alone that it was a Xenix syscall.
Is there any doc that can help me hacking this syscall into the ibcs2
emulator?

Are you telling me that the IBCS emulator is not really working?
Unfortunately I can't ask for a Linux version.
Have you ever had a look at the NetBSD one? Is it usable?
Thanks for your help.
