That is correct; the chip is both 5V and 3.3V capable but the 5V logic blocks 
are *not* certified by Xilinx to work in 3.3V systems.  I manually looked at 
the Voh/Vol, Vih/Vil and current specs on the I/O blocks and they seemed fine 
to me, so I went ahead and did it.

So really, Digium could dual-key the TE405P and take the chance, but I know I 
certainly wouldn't do it from a business perspective.

You'd have to see the card edge.  I couldn't find a picture of it on the web 
site.

That's exactly what happened to me.  I got the TE405P since *all* systems have 
5V slots but only a few have 3.3V ones.  Then my SuperMicro server came and 
all it had were 3.3V slots.  dammit!  :-)
