Well,
because no one gave me an answer I needed to get this cracked by myself ;-)

On host system I use gentoo-sources - 2.6.16-gentoo-r1. It looks that 
creating squashfs filesystem using the kernel and squashfs-tools-3.1_p2 
results in error while booting GNAP core remastered with any extension 
(including boa, dash, rrdtool delivered as examples to GNAP).

I've also tried using another system as host (2.6.17-gentoo-r7) and the 
results were exactly the same.

Because above error was about squashfs, I tried changing the GNAP kernel 
(I've chosen new gentoo sources 2.6.18). This resolved the problem, so I 
assume it was problem with squashfs mounting options in standard GNAP 
kernel. I find this as a GNAP bug, because it prevents anyone using some 
kernel versions using GNAP extensions or standard GNAP kernel. 
Unfortunately, I don't know how to resolve this problem permanently :-(
