LZX is not "unsupported". But to use it you should use cecompr.dll which supports that type of compression. Just put that dll wherever you want (in the kitchen folder) and define the path to it in Settings/XIP (second line from the bottom).
After that you can use LZX compression with predefined cecompr.dll
The default one from your OEMXIPKernel does not support anything but XPR.
I wanna underline that LZX compression reduces the rom image size but the device will run slower than with XPR.
LZX is useful for devices with small flash size and absolutely useless for HD2.
Example - when I make rom for Asus P525 - I for sure use LZX, but when I cook for Leo - I use XPR.
If you're interested in LZX - notify - I will attach the dll over here
