Every so often, a thread comes up in the Linux kernel mailing list about
modifying the kernel to run APM inside a virtual machine, since APM also
causes problems with SMP. There is already other code doing this, such
as (I think) the VESA framebuffer code and BIOS calls on other
architectures. Usually, the thread erupts into a flamewar about the
stupidities involved with running something inside a virtual machine
_inside_ the kernel.
Supposedly, ACPI will solve these problems, except that a) ACPI doesn't
work on my machine, and b) the user-space ACPI code was developed
independently from the APM code, and thus is incompatible. Go figure.
