The IDE->CF is probally your best option. If you can't find a small
PCI card with flash on it.
I think that in read only mode you probally won't have any issues. 
Especially since these things won't power cycle much...

However if you do have  a problem...

Bitworks, Inc has an IDE to CF adapter that we have used in some of
our products.  We call it the BitDrive.

We could modify this board for you so that it ran off the 12V supply
rather than the 5V and add in a 5V Linear LDO regulator with a large
cap on the 5V rail such that the CF would have lots of clean power
long after the main power died.  This should insure that the CF's
don't die due to power issues.

In qty. of 1000 I'm pretty sure we can be pretty close to the cost of
purchasing an off-the-shelf adapter.

Give me me a ring if your interested.

BTW.. We could also build you a low profile Flash memory PCI card but
I think that will be more expensive.
