Default 100% CPU usage on geforce 9600M GS

I have problems with stability of this driver since purchase laptop with nvidia. Tried various drivers, through long time always the newest beta from your ftp, now sticked to those from ubuntu repo, currently
195.36.24-0ubuntu1~10.04. Today again Xorg hanged due to nvidia driver, losing few hours of my work. Will this driver be ever in 50% as stable as Windows version? Although it happens once per few days I must save everything every 10minutes, can't left computer overnight or use clock alarm from KDE because I never sure if it will not hang kernel even doing nothing.

Here is a log from today's hang - kernel responsive, one core eaten by Xorg, KDE freezed not responding to keyboard, mouse except cursor moving, logged via ssh and attached gdb to Xorg process:

Where is the problem ? Funds, lack of debug or developers ?
Why you advising adding different options to kernel which limit functionality or interfere HPET what only decrease probability of deadlock not eliminating it, instead of debug and fix the issue?
