Fixed for os851.  Don't confuse the os851.usb files between XO-1 and
XO-1.5 though, since the laptop will gladly upgrade to a kernel that
won't boot properly.

Fixed.  The warning was wrong.

Takes about 350Mb, but it is not practical to explain exactly how much
space is required, since it depends on too many factors (other previous
olpc-updates in particular).  Yes, if there's not enough room it stops,
and after clearing some room it can be asked to continue from where it
left off.

I don't know of a guide.
