Oversight. Well, partially. One problem we have is that there are
still lots of drivers that have not been updated to take advantage
of the new device model, which includes setting suspend/resume
callbacks.  Which means you'll resume, and some of your devices
may or may not work again afterwards.

Another problem is we have three seperate implementations of
suspend functionality.

- CONFIG_SOFTWARE_SUSPEND
  Pavel's original version. No-one who has seen the code
  can hold their lunch. It's really ugly, I don't trust it a bit.

- CONFIG_PM_DISK
  Pat Mochels cleaned up version of Pavel's work.
  Not much better, but somewhat better.
  Pat no longer works at OSDL, and may not have time to continue
  this as much as he previously did, so this may or may not get 
  finished, depending on Pat's spare time.

- CONFIG_ACPI_SLEEP
  AFAIK, nothing to do with the above.


I'll turn on ACPI_SLEEP in the next build and see how things go, but
don't be surprised if this doesn't make it into the final FC2 tree, this
is an area of the kernel that still needs considerable work.
