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.
