The simple mode adds code to QEMU's x86 target that only exists to
support microvm. It should be motivated by a clear win in boot times.

SeaBIOS doesn't need ACPI. I agree that ACPI should be optional in microvm.

It currently needs PCI, but that's a one-line change to avoid panicking.
ACPI is optional, on the other hand qboot doesn't support mptable so
that can be a problem when ACPI is disabled.
