It's clever, but playing games with %ebp is not going to work with restarting of the system call - we need to restart with the proper %ebp. I pushed out the AT_SYSINFO stuff, but we're back to the "needs to use 'int $0x80' for system calls that take 6 arguments" drawing board. The only sane way I see to fix the %ebp problem is to actually expand the kernel "struct ptregs" to have separate "ebp" and "arg6" fields (so that we can re-start with the right ebp, and have arg6 as the right argument on the stack). That would work but is not really worth it.
