[mythtv-users] Suspend to ram with IONITX

OK, I got suspend to ram to work with my new diskless FE based on the
IONITX. I couldn't do this with my old frontend as it could shut down
(appletv) and this is my first foray into setting this up.

I hibernate to ram, works fine, but have to press the power button to turn
it back on.
System comes up and remote and audio work, which are 2 things I read people
have trouble with after resume.

I was looking up resume from USB/remote with the IONITX boards when I found
an "official" thread about the IONITX boards. From this thread I found out
that the original boards did not have the capability, crap. But, they
recently added Wake-on-USB on the V 01 boards. I checked, and I have it. It
is on by default, the JP3 jumper (only on the V 01) is set to 5V Dual by the
factory.

Ran a 
# cat /proc/acpi/wakeup
Device  S-state   Status   Sysfs node
SMB0      S4     disabled  pci:0000:00:03.2
USB0      S4     disabled  pci:0000:00:04.0
USB2      S4     disabled  pci:0000:00:04.1
US15      S4     disabled  pci:0000:00:06.0
US12      S4     disabled  pci:0000:00:06.1
NMAC      S5     disabled  pci:0000:00:0a.0
PBB0      S4     disabled  pci:0000:00:09.0
HDAC      S4     disabled  pci:0000:00:08.0
XVR0      S4     disabled  pci:0000:00:0c.0
XVR1      S4     disabled
P0P5      S4     disabled
P0P6      S4     disabled  pci:0000:00:15.0
P0P7      S4     disabled  pci:0000:00:16.0
P0P8      S4     disabled  pci:0000:00:17.0
P0P9      S4     disabled  pci:0000:00:18.0
PWRB      S4    *enabled

So I do
# echo "USB0" > /proc/acpi/wakeup
# echo "USB2" > /proc/acpi/wakeup
# echo "US15" > /proc/acpi/wakeup
# echo "US12" > /proc/acpi/wakeup

And now I have 
USB0      S4     enabled   pci:0000:00:04.0
USB2      S4     enabled   pci:0000:00:04.1
US15      S4     enabled   pci:0000:00:06.0
US12      S4     enabled   pci:0000:00:06.1

I then hibertate to ram, and watch as the system suspends and then resumes
itself without prompting from me.
Process of elimination identified the issue as US12 being enabled for
resume. Incidentally this is the one that the Streamzap is plugged into. So
I switch it, it is now in USB2, and the same issue again. This time tracked
back to the USB2 being enabled???

Does the Streamzap not support suspend?
If so, which remote do people recommend for resume?
