Does the first A20 card have a built in RTC?
I wasn't able to find the answer on either page for the card.
(I do believe I saw this question answered at some point.)

Follow up questions:
If no to the above, does the Flying Squirrel have an RTC to compensate?
Do future cards currently on the drawing boards have an RTC?
What is the policy on where the RTC should live?
The I/O board or the card?
Is it acceptable that neither have one?
Which wins if both have an RTC? (luck of kernel driver order?)
My answers would be:
I/O Board for all of the above, with no RTC at all being acceptable
(think router). I favour the I/O board as usually has the luxury of
space to include it. It's also a part of any design that won't change much.
