--- Comment #3 from Hannes Hauswedell <h2+fbsdports at fsfe.org> ---
It actually gets past the real time clock, verbose boot shows it hanging at:

atrtc0: <AT realtime clock> port 0x70-0x77 on acpi0
atrtc0: Warning: Couldn't map I/O.
atrtc0: registered as a time-of-day clock (resolution 1000000us, adjustment
0.500000000s)
ioapic0: routing intpin 8 (ISA IRQ 8) to lapic 4 vector 48
ioapic0: routing intpin 8 (ISA IRQ 8) to lapic 0 vector 49


Trying NoACPI+Safe mode results in a kernel panic:

Timeout initializing vt_vga
KDB: debugger backends: ddb
KDB: current backend: ddb
panic: running without device atpic requires a local APIC
cpuid = 0

SafeMode-only boots the system a lot further, but it then hangs on mounting
