A better phrase would be "adequate support for ACPI".
I use it on my desktop and server machines, where I can -- sometimes --
get temperature monitoring and power-off. I can even associate a
script with the power button, which is very nice.
However... it's useless to me on laptops. I can't do suspend/resume
on my Thinkpad T42, for example. More precisely, I can suspend and
resume, but if I do, I lose my USB ports. That's completely
unacceptable to me, given how I use my machine -- sufficiently so that
if I had to buy a new Thinkpad today (and I plan to by the end of the
year), I'd have to switch operating systems. (There's a minor glitch
in that while I can suspend by closing the lid, opening the lid doesn't
resume; I have to hit the Fn key. That's a slight nuisance but one I
can easily live with.)
The ACPI battery status monitoring is ok but not great; it doesn't
detect battery changes properly. I haven't tried a docking station --
what does OpenBSD do? One thing I *really* miss -- the ability to swap
what's in the Ultrabay -- a battery, an optical drive, a second hard
