I started coding this and ran into a problem. According to Kevin
the stack is too small for a one sector buffer. So I was going to
use an aligned subset of the caller's buffer to read the last
sector and save its last word in a stack variable. But if a
single sector is requested and the buffer is unaligned, aligning
it results in a buffer too small to read a complete sector.

Thanks,
