reformatting laptop & ACPI: special partitions?

[Michael A. Smith]

My laptop (Sony VAIO FX-101) has been happily running FreeBSD since 4.3 
(it's currently running 4.9-STABLE). I've never really bothered with 
power management (apm, acpi, etc...), since I always use it plugged in. 
That may change, however.

I'm wiping the hard drive and installing FreeBSD 5.2.1 from scratch, I 
want CardBus and Wi-Fi. I may also start fiddling with ACPI. I've read 
that some laptops use special partitions to store the contents of RAM 
when hibernating, sleeping, coma, whatever...

Does anyone know anything about this? Should I make a special partition 
for this kind of thing? Where? (first? last?) How big? What kind of 
partition? (FAT32? FAT16? UFS?)

As I recall, when I got the laptop, it did NOT have any special 
partitions (I wiped it the day that I got it and installed FreeBSD).

Any suggestions would be helpful. Thanks!!
