I've already looked around on google but I didn't find anything about such
kind of partition on Toshiba machines (there are bunches of articles talking
about IBM and Dell). Is it possible to guess the type and size of this
partition by any chance if I assume this is the case? Say if I create a
partition (primary? or logical partition?) with exactly the same size of the
physical memory, and then try labelling the partition with random types
until the BIOS recognises it? I am just wondering if there's a general idea
what this partition would be look like.

Yes, sounds like you need a suspend partition.  Perhaps Toshiba has a 
utility on their website to build this.  Alternately, if you know the 
partition type you can use fips or Partition Magic to create one 
manually.  Be careful not to damage your partition table and lose data.
