One approach uses ring-1 trampoline, the other one doesn't. The posting I pointed to, was explicit about the stack usage, but as for the ring-0 approach while still using the kernel stack - here it is: http://www.ussg.iu.edu/hypermail/linux/kernel/0410.0/1402.html
Is this what you mean? This is pretty much all about it, the third approach is in the kernel, and there were no more, even under discussion.
