Well, with symptoms like those exhibited (where not every sleep results in blue screen), it's hard to diagnose with complete certainty.. BUT preliminary results are looking promising :)

Basically, laptop's been in sleep mode (on battery too) for maybe an hour. Previously, it seemed like any sleep (over 1 minute to be sure) would cause system collapse (usually a few moments after awaking and returning to previous state, ie no pwd/login...). Having said that, immediately after installing the Intel RAID driver (and the install automatically identified the SATA controller to update), I've just resumed from sleep without a blue screen (kernel inpage or critical object termination) for the first time in .... eons!


Monitoring and comparing (I'm not using the RAID drivers on the old build, that isn't exhibiting issues).


Will post results of the big test (resume from a full night's sleep!)
