There is one basic problem; the i386_modify_ldt() Linux system call isn't emulated due to the current implementation of its counterparts under FreeBSD. (The code in question uses copyin/copyout to access call arguments.) If you were to take a stab at this (I can provide details on the Linux call interface if you don't have them already), I *think* that much of the rest of it would be quite happy. I know you have some x86 experience, and at least a little time on your hands, so this would be greatly appreciated! mike
