Linux "fast boot" is purely a software feature.  The most significant
hardware feature is a BIOS which doesn't take too long before it loads
the kernel.

Possibly the marketing people have confused you with their use of the
word "supports".  The closest match to "supports intel fast boot"
would be "supported by Moblin".  Moblin is the optimized distribution
initially developed by Intel.  One of the optimizations was to limit
the supported hardware configurations.  Intel Atom boards were
obviously favoured ;-).  Cynicism aside, it's well worth a look.
