I'm not really removing smbus stuff at all. but the ram stuff should
use spd_read_byte, so you can fake it out as I am doing on alix1c and
as we have done on other platforms.

So if you are doing stuff that is spd-related, you really should use
spd_read_byte, since some systems don't even have an smbus.

If you are doing smbus stuff, by all means use smbus functions.

Make sense? Did I do the wrong file or something?

[note: IIRC, you're the guy who told me to use a fake spd function --
you or Marc :-)]
