So I applied your patch, Nate's patch, removed spinlock_enter() and
spinlock_exit() from OsdSynch.c and tried to to play a little with
booting with ACPI:
For the first time I could boot with ACPI and login to the system. But
after several minutes I was unable to enter any symbol from the
keyboard, however was able to switch between consoles (alt+Fx).

Couple times got kernel panic:
---
panic: _sx_xlock_hard: recursed on non recursive sx ACPI embedded
controller  @ /usr/src/sys/modules/acpi/acpi/../../../acpica/acpi_ec.c:209

cpuid = 0
KDB: enter: panic
[thread: pid 8 tid 100018 ]
Stopped at          kbd_enter+0x32: leave
db>
---

and couple time booting process stops at the different stages (but
before the login prompt), I was able to print from keyboard, symbols
appeared at the screen, however system did not do anything except
this. There were no errors in the logs (console.log, messages)

Many-many thanks :-)!
