K8 RAM init debug messages are pretty short and sometimes cryptic. Make 

them a bit more verbose and hopefully more understandable.

Old messages for my machine with 5 GB:
RAM: 0x00400000 kB
Ram3
[...]
Initializing memory:  done
RAM: 0x00500000 kB

New messages:
RAM end at 0x00400000 kB
Adjusting lower RAM end
Lower RAM end at 0x003f0000 kB
Ram3
[...]
Initializing memory:  done
Handling memory hole at 0x00300000 (default)
RAM end at 0x00500000 kB
Handling memory mapped above 4 GB
Upper RAM end at 0x00500000 kB
Correcting memory amount mapped below 4 GB
Adjusting lower RAM end
Lower RAM end at 0x00300000 kB
