I've noticed that getsecs() gave a bit strange results on my turbo.

Rearranging the RTC subbytes in the secs value made things consistent for
me.

Could anyone check whether this is different on non-turbo hardware?
An easy way to check is to break into DDB and just call getsecs()
repeatedly. If the result doesn't get get incremented secondly, the
following patch should help.

(The diff is against (around) 1.5U, with support for RTC_OFFSET thrown
in.)
