After BIOS upgrade and also reduced the AGP aperture size the memory layout
look much much better :-)!!!
Current is:
Memory: 3892196k/3930304k available (2049k kernel code, 36744k
reserved, 765k data, 228k init, 3012800k highmem)
The previous one was:

reserved, 765k data, 228k init, 2432132k highmem)
so I got other ~570Mb. That's nice :-)!
