Basic block allocation for physical memory allocation.

Browse Source 
- 1 block = 4096 bytes : because this will make page fault handling possibly
somewhat easier

- 1 byte in the bitmap = 8 blocks of physical memory

unsure if the allocation is perfect ... guess i'll find out some day if this is actually correct.

The bitmap needs 16kb to keep track of 2gb of physical memory. Seems a decent percentage to me.
