My Laptop is dell inspiron 1464 with 10.8GM.

With hibernatemode = 1 ( write memory to /var/vm/sleepimage then shutdown ),
when trying to resume(press power button), chameleon log gives an error
Reading image file /var/....../ blah blah blah, 512 bytes.. blah blah...
Header read size 200
Incorrect Image Signature
and then goes to normal boot.

With hibernatemode = 0 (keeps memory active while shutdown LED and harddisk), and wakeup is perfect.

In org.chameleon.Boot.plist there is
darkwake=0
USBBusFix = Yes

smbios is set as MBP61
2 USB highspeed recognized as extended(EHCI?)。
chameleon version: r2033

In Windows 7 i can confirm that the power management S3 mode is supported while S1/S2 not, and the hibernate works with Win7.
But in BIOS settings there is no option for this.

Why it does not work on 10.8? In 10.6 the deep hibernation works fine on my laptop.
I do not know if the info is enough, please let me know if more info is needed.

CPU i5-430m, speedstep works with ssdt,
audio alc269 working with patched applehda,
ati 4330m works with modified ati4600controller.kext

In the attach there is my DSDT file.

Yes, I had already disabled the encrypt swap, but still not working.

Try this:
fsck -fy
mount -uw /
rm /var/vm/sleepimage
reboot

I thought this is used for when booting into -s mode.
Anyway, I will try this, first boot into single mode, delete the sleepimage and reboot, and then try deep hibernate.

Easy way for this is to change Chameleon with new version

I had already updated the latest Chameleon r2041 from r2033 yesterday and still not working

This is very strange.

I fixed it on my computer by manually removing the sleep image file.
