>Description:
The system is running on a motherboard asus m2n-sli deluxe with chipset nvidia 
nforce 570 sli mcp

I have two solutions:  booting with acpi or booting without acpi.
If I boot with acpi, after booting is complete, I have to wait for 50 seconds, 
with black screen, until xdm starts.  During booting, the /var/log/messages 
shows:
Jul  3 22:07:35 comete /netbsd: pckbport: command timeout
Jul  3 22:07:35 comete /netbsd: pms_enable: command error 35
Jul  3 22:07:47 comete /netbsd: pckbport: command timeout
Jul  3 22:07:58 comete /netbsd: pckbport: command timeout
Jul  3 22:07:58 comete /netbsd: pms_disable: command error
Jul  3 22:08:10 comete /netbsd: pckbport: command timeout
Jul  3 22:08:10 comete /netbsd: pms_enable: command error 35

If I boot without acpi, there is no problem and xdm starts immediately after 
booting.

Concerning halting the system:
if I boot with acpi, poweroff works normally and the system is halting and the 
pc goes power down.
if I boot without acpi, there is always a problem, if I use halt or if I use 
poweroff to halt the system:

for example, if I use halt, this message is displayed:

ACPI Error (hwacpi-0156): No SMI_CMD in FADT, mode transition failed [20080321]
ACPI Error (evxfevnt-0221): Could not exit ACPI mode to legacy mode [20080321]

or if I use poweroff, this other message is displayed:

Here the system is freezed.
