Yes.

From following this list, it sounds like ACPI in FreeBSD is horribly broken on 
the vast majority of modern laptops.  I am fortunate enough not to own modern 
laptops. :-)

On my Toshiba Satellite 1605, ACPI suspend (to RAM and to disk) works 
flawlessly.  It's worth noting that ACPI suspend-to-disk is several times 
faster than APM suspend-to-disk.  This machine now runs Gentoo, however, 
because of the lurking M5237 USB bug (which I've finally gotten offers for 
help on, six months later, but can't have the downtime required to reinstall 
the OS twice to test).

On my IBM Thinkpad 755CX, APM suspend (to RAM and to disk) also works 
flawlessly, and is much faster than the Satellite since it's maxed out with 
40MB of RAM.  :-)

I recently picked up an HP Pavilion N5290 (like the other two, it died and was 
discarded by someone who couldn't solder); it's running Gentoo by default 
after my issues with USB on the Satellite, so I can't comment there.  
Hardware suspend doesn't work -at- -all- on it in Linux, but software suspend 
in their kernel does.  You just have to manually patch your kernel to do it.  
Whee.
