ACPI is definitely a mixed bag. I don't think I've ever seen a system where it worked completely right, unlike APM, which was pretty mature.
Most laptops now days need it. Period. End of story. If you don't run it you get stuttering sound, jerky mouse pointers, dead or flaky usb ports, etc, etc.
Oh, I know. My Thinkpad T22 is sort of one of them. Under SUSE 10.1, if I turned off ACPI and turned on APM, I could get working suspend, but I had to disable CPU frequency switching in the BIOS or things got wonky when I switched from AC to battery. In 10.2, suspend doesn't work in APM, either. Suspend/resume have been gradually getting less reliable for me with every new release, which makes me wonder if the Linux developers have sort of given up on the whole thing as a bad job.
I know the SATA driver team has been working on suspend / resume since last summer. I don't think it was really supported with sata before that. They definately don't have it working perfectly yet, but at least they are testing it and getting new fixes in with every release of the vanilla kernel. The ide driver was officially unmaintained from June 06 until a month or two ago, so IDE support had likely been going backwards during that time (2.6.17 thru 2.6.19 I think saw no real IDE driver work). FYI: Laptops started shipping with internal sata drives last summer as well. I think that was the impetuous behind the sata driver team getting to work on it.
