2. Display module capacity in GB if it is at least 1GB.
3. Indicate if a memory module is "registered".
4. For DDR3, indicate if a temp-sensor is present.

1. Use proper CRc check for FB-DIMMs rather than simple checksum
2. Provide access to entire SPD ROM contents via sysctl, rather than
only the first 64 bytes
3. Use macros to define i2c bus address checking
4. General fix-up for RAMBUS memory (not that anyone I know has one)
