Thanks;

at least i didn't encountered anymore ofs panic but in grub rescue sheel 'ls' just return an empty line;
I can just grab 'lsmod' info:
sh:grub> lsmod
Name    Ref Count       Dependencies
linux   1               boot,elf
elf     2               gzio
gzio    3
ls      1               normal,extcmd
extcmd  2
sh      1               normal
normal  4               boot
boot    6
part_msdos      1
fat     1
minicmd 1

but if I try to add another module (e.g. scsi or what else) it always respond:
"error: invalid arch independent ELF magic"
