Default nVidia driver + hibernate = no go?

Hi all!

Some tech details for a start:
* Computer: Lenovo T61
* Linux xxx 2.6.23.15-137.fc8 #1 SMP Sun Feb 10 17:03:13 EST 2008 x86_64 x86_64 x86_64 GNU/Linux
* 01:00.0 VGA compatible controller: nVidia Corporation Quadro NVS 140M (rev a1)
* Driver versions I've tried: 169.09, 169.12, 171.05

After resume from hibernate screen stays blank, keyboard doesn't work, even CL or NL doesn't respond. Only thing I can do is press ctrl+alt+delete and it reboots. I'm able to ssh into the box, X is taking 100% of the CPU and I get this in kernel logs (it's present like 5 times):
Code:
BUG: soft lockup - CPU#0 stuck for 11s! [pm-hibernate:6746]

I have searched forums and internet for a simple solution - how to get hibernate (suspend to disk) with nVidia driver? I have not found any solution that would make hibernate work, nothing.

I am able to hibernate with vesa driver, I saw Intel cards hibernating fine, even ATI does this quite good, what is happening to nVidia?
I see bunch of people with the same issue - they can't hibernate a nVidia powered laptop with official drivers enabled!


Hibernate is quite important to laptops, personally I can't do my job w/o it
Btw, I didn't saw any nVidia staff comments to hibernate issues others filed (even with proper bug report file) and that's really sad!

Can someone tell me: is nVidia aware of this, will there be a solution at all, some estimate, workarounds? Anything...

Thanx
