Flashing a .kdz file will install a baseband.
For example, if you flash V20C, you'll get the V20C baseband. Same for every other .kdz file.
Now, many users noticed that on STOCK Thrill, when they were to flash a P920 version of CyanogenMod, they wouldn't receive service at all.
The reason was because it was flashed via ClockworkMod.
Currently, ClockworkMod does NOT flash basebands and that was the reason why.
It is the same concept with this kitchen. Since it is flashed in ClockworkMod, the baseband will NOT be flashed over, therefore, increasing the range of basebands this ROM can be used on.
In short, it is compatible with EVERY Gingerbread baseband.
Please do not ask if it is compatible with your baseband. If it's a Gingerbread baseband, the answer is YES.
