Hi,
we're starting to see systems where the legacy BIOS is broken (regarding
interrupts in my case), and we have to use a ioapic+ACPI kernel to get
devices working properly (in my specific case: on the newest supermicro
mainboards, the legacy interrupts for wm0 and wm1 are swapped; because of
this the kernel enters an interrupt a soon as one of the interface is
configured).

Shall we provide a INSTALL.ACPI kernel ? Of couse this also mean we have to
be able to boot it. In my case I use PXE so it's not an issue; I don't
know if the boot loader can now select different kernels from a cdrom boot.
