Yes, WiFi will be broken on any newer builds. In 10.2 it assumes a kernel module and now it assumes that the WiFi driver is built into the kernel.
In addition to WiFi issues, I would expect some oddities in the display. These may get worse on the next round of builds.
For the time being, you'll need to be patient. Any time I spent on a custom kernel would mean less working on getting our device supported properly for CM 11.
