[PROBLEM] Installing libwebkitgtk

[Danny the Hound]

I have XBian 1.0 (knockout) on my Raspberry PI B, and I would like to install some lightweight browser with javascript support (which I would then run through vnc). Right now I'm using Iceweasel, but that one is quite slow, so I was thinking about installing surf, Epiphany or kweb. Problem is all those are webkit based and when I'm trying to install them through apt, I'm getting into a conflict. They all need libwebkitgtk-1.0-0 (>= 1.3.10), but that one depends on libegl1-mesa (>= 7.8.1) or libegl1-x11 and libgles2-mesa (>= 7.8.1) or libgles2 which are in conflict with xbian-package-firmware. According to its description, this one, however, should provide libegl1-mesa and libgles2-mesa. Is there a way I can make libwebkitgtk correctly install even with keeping xbian-package-firmware?
