474 help
475 Enable the PM code's memory area checksum over sleep. This option
476 will generate CRCs of all blocks of memory, and store them before
477 going to sleep. The blocks are then checked on resume for any
478 errors.
479
480 Note, this can take several seconds depending on memory size
481 and CPU speed.

490 Set the chunksize in Kilobytes of the CRC for checking memory
491 corruption over suspend and resume. A smaller value will mean that
492 the CRC data block will take more memory, but wil identify any
493 faults with better precision.
