freebsd stable - Sep 2008 - ACPI sleep broken on ASUS Vintage AH-1

Hi,

Just noticed that when I try to ACPI-sleep an ASUS Vintage AH-1 based 
desktop system, that I get the following message:
    acpiconf: request sleep type (3) failed: Operation not supported

Supported sleep states in sysctl:
    hw.acpi.supported_sleep_state: S1 S3 S4 S5

This is an amd64 uniprocessor system running 7.0-RELEASE. BIOS version 
is 0303 (last release), it is an AMI BIOS. I've seen S3 sleep work fine 
in Windows XP on this box.

I would really like to be able to sleep this box rather than up/down it, 
as it's in my home, less noise, less power consumption etc.

Any further info needed let me know.

thanks!
BMS

Currently, suspend/resume is unsupported on FreeBSD/amd64, as nobody has
yet written the amd64 equivalent of sys/i386/acpica/acpi_wakecode.S.
NetBSD has this code, I'm not sure how easy it would be to port it over
or if it would be easier to write it from scratch.
