Sounds like the BIOS is stealing 64MB for video RAM.
There's likely a BIOS setting which governs the size of this.

As for not being able to access all 4GB, this is a FAQ.
If you run a 32-bit system, the top gigabyte or so of address space is
reserved for memory mapped I/O reservations like AGP, PCIe, etc.

If your hardware is capable of running in 64-bit mode, do that.
