So I'm back with updated system:
$ uname gives me 2.6.35-rc3, where Linux 2.6.35-rc6 (object 
b37fa16e78d6f9790462b3181602a26b5af36260) is used as base for nouveau-master 
with HEAD 439a21f25f60221e6d9032cb8ad3bb1aafee44ea, nouveau kernel modules 
compiled in;
libdrm 2.4.21-r1 from gentoo x11 overlay;
xf86-video-nouveau 0.0.16_pre20100615;
x11-base/xorg-server-1.8.99.905 from overlay too.

Yes, that problem with cards initialization is gone!

But now I'm at the "next level of trouble": 
1. when two Xservers are running, after some minutes video output of the 
primary card ceases (logging out restarts X and then it's back..), while the 
second output is still ok;
2. after hibernation/resume the same problematic video output is showing me 
some vt with my X11 mouse cursor and gpm's one in the same time, all input is 
directed to X11, but no useful video output for primary card, while second 
output is ok (again X restart helps).

What would you suggest me now?
