No.  The card disables interrupts and does not re-enable them until the
boot sequence is almost done.  The thermometer runs by getting interrupts,
so there is no thermometer.  Amuch more serious consequence of this
is that you cn set up an AppleShare volume to be logged on at boot time,
but the CMS card will turn off interrupts, and the AppleShare init will
hang.  This is VERY annoying.  The way we fixed it is we made sure that
one of the init's (GSbug) that enables interrupts gets run FIRST.
