I think qemu's ACPI emulation is broken with
newer our acpi implementation.
With ACPI enabled kernel the pci bus is not probed
(then neither vga and it causes the panic).

Booting a kernel with -2 (disable ACPI) works.

qemu doesn't emulate delay on BIOS either, so you have to
boot the default kernel first, reboot again, and then
hold space to get boot prompt.

There is the similar device probe problem on i386 emulation:
