So I should go and fix it ;-). (I'm now overloaded with email sorry
for being terse.)

Can we do something like

+ Enable the suspend to disk (STD) functionality.
+ In principle it does not require any support from BIOS, although
+ ACPI will be used if available.

+ You can suspend your machine with 'echo disk >
+ /sys/power/state' after placing resume=/dev/swappartition on
+ kernel command line.
+ Alternatively, you can use the additional userland tools available
+ from <http://suspend.sf.net>.

(and remove ...upon next boot... section).

+ It is possible to boot without resuming and resume later but
+ if you access any partitions/files used by suspended kernel,
+ you'll probably loose your data. See ... for details.
