I patched mine on Sunday and installed this firmware. I can't live without both page buttons go next and a few other bits. All worked for me. I can't say I have noticed any difference in this firmware.
I downloaded the new firmware and installed it on my Libra Colour. Then copied the downloaded firmware into the correct folder in the patch structure and just renamed the zip file to that of the old firmware I previously used to patch and reran the patch file, as explained by Slantybard here :
