APM is still there and not going away soon as many of the older BIOSes out there don't have ACPI. You need to use one or the other, not both, but which is appropriate is dependent on the laptop and it's BIOS. Many laptops with ACPI capabilities still run better on APM. Getting suspend/resume to work on ACPI is still problematical on may laptops that do support ACPI. On the other hand, ACPI seems to work fine on my 600E these days, although I'll admit that I don't pull it out of the drawer very often. ACPI didn't work in the past, though. Maybe: FreeBSD supports APM on certain machines. Please look in the LINT (V4.x or the NOTES (V5.x) kernel config file, searching for the APM keyword. Further information can be found in &man.apm.4;. FreeBSD 5.X and later support the ACPI features found in most modern hardware. Further information can be found in &man.acpi.4;. If a system supports both APM and ACPI, either can be used. You will probably want to try both and use the one which works best for your system. In any case, the word "supports" in the second paragraph should be changed to "support" for proper agreement with the subject. -- R.
