I pulled the card and found the following chips:
SAA7135HL/203 (CG2548 13 TSG06302)
COMPRO PRO1A 0643D
WJCE6353 (W620AA17) (Codfam decoder?)
ATMEL642 (EEPROM?)

Plus 2 ICs which have been defaced.
One is a SO-14 package and looks like it might have a Philips logo on 
it  It might be a 74HC74N.  The 74 can be read.  The letters are a bit 
harder to make out. I don't know why they would need to deface that.
One is a SO-8 package and although you can see writing, it can't be read.

There are also 2 metal enclosures.  Much smaller than any I have seen 
before.  They are both 36mm x 26mm x 5mm. I have not tried opening them.

I forgot that the card also has a wake up clock.  You can connect it to 
the atx power switch and it can wake up the machine at a specified time. 
(Might also support PCI wake up).

Other interesting things (all might be crystals):
4.0F6L
32.1F6L
S6X3
NSK 6JLA Z 20.4800
