I am terribly surprised that Linux doesn't yet support "suspend to disk", also
called "Hibernate mode"; When I installed FreeBSD 2.1.7 on an old 486, it
liked hibernate just find.. though sleep/suspend did not.  I hope to see it
soon, and I'd like to be able to add a feature, wherein you'd have maybe 20
meg of flash ram that the hibernate data is written to, as opposed to the hard
drive-- that way it could resume from hibernate theoretically almost
instantaneously.  This may be the perfect thing on the JumpTec DimmPC 486-- it
has 16 meg of flash on card accessed as the primary IDE.
