Log:
Fix the 'write-with-rule' operations to not do an unneeded read first.
eg: to write an 8 bit value to an 8 bit register, it was first reading
the old (8 bit) contents, "merging" the new 8 bits in (ie: complete
replacement) and then writing the new value out.
This was breaking the SMI call on my VAIO PCG-F690, causing the system
to hang during boot.
