I have been running the UNI kernel on my T43 for a long time, APM works, and it suspends (no ACPI!!). I'm just curious as to whether that m8ght fast track the APM support under SMP for the T60/61, T400/500, related systems, and some desktops.

If you plan to use SMP, do not install APM.
So IIRC, under advanced install, APM is selected by default and ACPI is not. Am I correct in understanding you are recommending unselecting APM at this point in the pre-install screen?
Absolutely. The SMP kernel, which was developed for Warp Server, never expected to be suspended or throttled. Pasha is working on a patch, but I don't think it is complete yet.
I am not sure if the UNI kernel had the same APM support as the W4 kernel. It is about 3K less in size. The SMP kernel is aobut 50K bigger than either of the others. I am pretty sure most of that is code for supporting multiple processors. Is the APM support on your T43 the IBM or eCS APM code? The IBM APM code did not know what ACPI was. However, one of the options for OS2APIC.PSD was /APIC.
