It depends on the driver you're using, actually. If the device is called
"hd", it's using a driver from the old IDE module; if it's called "sd",
it's using the newer libata module. The former is considered unwanted
legacy, and it's drivers are by now mostly all ported to libata. That's
why the device names change when booting into the new LFS compared to
building it from the host - the host used the old driver, LFS uses the
newer one.
