This is more of a status update than any major breakthrough.
I got the IR working under linux by using an existing card type. I also
got regspy on windows working but it only shows some GPSTATUS bits
changing when the IR program is running. The only other change seen was
in SAA7134_TS_PARALLEL but more on that below.
The Compro windows software will not run without a sound card. That
took some time to figure out and solve :-( It is also buggy and prone
to lock up and crashe, but hey, that is why I use linux.
I found the regspy tool from DScaler but it does not officially support
the 7135. It did however work and show the following:
SAA7133 Card - State 0:

The only bits of GPSTATUS which change are
0084c700
0084c700
0284c700
0684c700
0884c700
0894c700
Unfortunately it changes too quick to capture the sequence and regspy
logging is a bit limited. Still, it shows the bits, and IR seems to
work already under Linux. Perhaps a conclusion that this has the same
or similar GPIO layout to other compro cards.
When changing from analog to digital, the SAA7134_TS_PARALLEL changed.
e4 was for DVB but I didn't capture the analog :-(
I think I'll put the card back into a linux box and try hacking some
things together.

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

I have recently been given a Compro VideoMate T750 to get working
with Linux. Unfortunately it is not yet supported by the v4l-dvb
drivers.
This is an Australian card has the following features:
- Analog TV Tuner (PAL-BG?)
- Analog TV Capture (SVideo & Composite)
- FM Radio
- IR
- DVB-T * 2
I have tested a few similar cards using the Mercurial drivers and the
analog capture works. I have not been able to get the DVB working
(which is what I want the most).
I am prepared to do whatever testing is required to get this working
but I was hoping there was a saa7134 expert who could suggest the
best way to go about it.
The card is currently installed in my linux dev box but I can pull it
and/or stick it in a windows box if necessary.
I have used btspy under windows in the past to figure out bt878 based
cards. Is there a similar saaspy?
