Graphics reinit, dumping graphics contents back into RAM, us resuming
devices in series, that kind of thing. On some hardware you'll spend a
noticable amount of time in the BIOS before any of the Linux resume code
gets touched. I thought the XO had got sub second, but I wasn't sure
that they were in the low ms range.
