Even better yet, is the announced Intel 80386-SL.  It is designed specifically
for laptops, and has power management built into the chip.  The power  
management uses its own interrupt that has a higher priority than NMI.  When
the power management interrupt occurs, a separate memory space is mapped in
(not swapped) to the user real-mode space.  In this manner, it is possible
to have a power management BIOS, and have the power management features be
totally non-intrusive.  The '386-SL supports 32MB memory, and is a fully
static device.
