There are two unofficial variations available that I made
to use Gecko 1.9.1.x in Linux with the wine emulator,
K-Meleon-F354 based on Firefox and K-Meleon-SM2pre based
on the new Seamonkey.
Download K-Meleon-F354 here :

Download K-MeleonSM2pre here :

Read the notes in the respective threads in Forum General.
Both variations are also usable in Windows.
