There's a chance that Daniela Engert might take on building an ACPI PSD. That would be interesting, because OS2APIC.PSD is one of the key files that permits SMP on SMP OS/2, the other ones being os2krnl, os2ldr, and doscall1.dll. I don't know if she'd be trying to deal with SMP or not, but might be because one of the motivations is to get to work with Hyperthreading. The big question is whether she has the time to do it or not. That would be quite cool as it could go a long way to fixing the power management issues around a lot of the newer computers too, and mean that OS/2 will continue to run on x86 for a while to come; as "legacy free" machines (ie- ones where you can't tell the hardware what to do;) become more and more common.
