In order to help people fix their touchpad problems I will attempt to keep up with the development and post any fixes for common problems here. If you have an issue please read this ENTIRE OP and search the dev thread of the ROM you are using to see if it was fixed there. The answers here are for the masses and there will DEFINITELY be cases where these will not work. Each device is a little bit different.
IF YOU ARE RUNNING A NIGHTLY EXPECT TO HAVE ISSUES
CAMERA AND MIC DO NOT CURRENTLY WORK. DO NOT ASK FOR ETA's OR HELP WITH THOSE.
RANDOM REBOOTS
The minimum CPU frequency is set to 192MHZ and it is to low for some devices. Try using a CPU contoller like SetCPU($$) or System Tuner (Free) to change it to 384 or 432. Those seems to be the best to stop this. It could also be due to the max being too high. 1.7 seems to be the highest you can go before having issues. If you still have issues at 1.7 try 1.5
Can't transfer files
USB Mass storage does not currently work without some voodoo magic. Instead go to settings > storage > menu (3 dots, top right) > USB computer connection and select Media device (MTP). You may also need to turn off USB debugging at settings > Developer Options
WIFI Loses connection
Known bug. To get it again forget your network, turn off wifi, turn it back on and reconnect. You might need to do this a few times.
Moboot still shows (Other ROM Name here)
Get an app like Root explorer and navigate to /boot, change to R/W mode and delete UImage.(OTHER ROM NAME)
I want to change what boots first
Get an app like Root explorer and navigate to /boot, change to R/W mode, open moboot.default and change to whatever ROM you want depending on your preference. Be sure to type it in EXACTLY as it is in the /boot directory. So if it is UImage.AOKP make sure to enter it into the moboot.default as AOKP and not Aokp. CaPs matter.
It sounds like my touchpad is farting/Has Scratchy sounds when I have sound coming out of the speakers
Common issue. Usually only happens when the screen is off. I have had luck fixing this by turning the sound down a notch or two but others have not. If it happens when the screen in on stop whatever is making the sound and restart it (pause/play music). I use Google music a lot so I set a tasker profile to keep the screen on when music is playing. Makes it easier.
I am stuck at a boot/loading/whatever screen. The device screen/buttons are completely unresponsive
Hold down power and the hardware home button for a few seconds and it will reboot. This is a firmware hard reset and should only be used in the most dire of circumstances
It won't charge!
Make sure MTP is enabled. See instructions above. This is one of those "It works but I don't know why" type of deals.
No sound when using headphones
Plug in your headphones before you start the app with sound and it will work. You may need to force close the app to clear it from system memory.
No sound after touchpad goes to sleeep
boot up touchpad with headphones plugged in
Power options do not work
Flash this in CWM. Be sure to make a Nandroid first in case of issues.

Getting a "SD card Removed" Message in notifications (ONLY WHEN YOU HAVE LOTS OF APPS ON SD CARD)
Follow this guide. It says it is for CM7 but works for CM9

Scroll down the the middle of the page and select the latest version of flash for Android 4.0
I will add to this as more problems are fixed/found a workaround for. If there is any other things I have missed please let me know.
Have fun and stay hairy
