Choosing between DELAY(useconds) and pause()

It appears that the pause() function cannot be used in driver functions which are invoked early in the boot process. Is there is a kernel api which a device driver can use to determine whether to use pause() or DELAY(), for delays which are say greater than 10hz - may be even 1 hz ?

Cheers,
David S.
