nsleep isn't known here as a function, only references i found is maybe
in posix-timers.c.

msleep() is known, but each time i add for ex.
msleep(100);
in any place in text_poke and/or text_poke_early it get a kernel panic
on boot. Here's a screenie:

I also tried to work with the isolated changes we have last made, but it
seems that only the 3 changes together work.
Also i tried to went back to older versions of alternatives.c referenced
in:
http://git.kernel.org/?p=linux/kernel/git/stable/linux-2.6.26.y.git;a=history;f=arch/x...

But with my few knowledges i ran in too many errors.

So, have you any further ideas, code that i/we could test?
Or - i'm naive - are the "3 changes" we made ready to go in the kernel
without to harm something real important than virtualbox?
