acpiconf Question Release 8 amd64 Nvidia Driver

Hello,

I am wanting to double check and see if there is a way to get acpiconf to go into standby or suspend while using KDE 4, SMP and the proprietary nvidia driver on [CMD="uname"]-a[/CMD]
Code:
FreeBSD freeenv 8.0-RELEASE-p2 FreeBSD 8.0-RELEASE-p2 #11 r201748: Mon Feb  8 12:46:39 EST 2010     
[email]root@build8x64.pcbsd.org[/email]:/usr/obj/usr/pcbsd-build80/fbsd-source/src-release/sys/GENERIC  amd64

[CMD="sysctl"] hw.acpi[/CMD]
Code:
hw.acpi.supported_sleep_state: S1 S3 S4 S5
hw.acpi.power_button_state: S5
hw.acpi.sleep_button_state: S1
hw.acpi.lid_switch_state: NONE
hw.acpi.standby_state: S1
hw.acpi.suspend_state: S3
hw.acpi.sleep_delay: 1
hw.acpi.s4bios: 0
hw.acpi.verbose: 0
hw.acpi.disable_on_reboot: 0
hw.acpi.handle_reboot: 0
hw.acpi.reset_video: 0
hw.acpi.cpu.cx_lowest: C1

[CMD="pkg_info"]| grep nvidia-driver[/CMD]
Code:
nvidia-driver-195.36.15 NVidia graphics card binary drivers for hardware OpenGL ren
I have compiled the nvidia driver from ports with the 'Enable support for ACPI Power Management' option marked yes.

Issuing [CMD="acpiconf"] -s 1[/CMD]
Code:
acpiconf: request sleep type (1) failed: Operation not permitted
Any suggestions are greatly appreciated. Thanks
 
The nVidia "blob" driver has been known to cause these sort of problem.

To test if this is the case, try exiting X, kldunload-ing nvidia, and put the system in standby using zzz or acpiconf.
