L4Android performance issue

I just got a chance to run both L4Android and Android-x86 on an Asus EEE PC to measure their performance. In short, it seems to me that 
mag is causing some problem.

I ran the Android web browser, and measured the page load latency to measure the performance of both system.

I tried to keep the configuration of both side the same. For example, both system only use VESA, and they share the same userspace binaries.

L4Android did well in some cases, however, I saw more than 2x slow down from L4Android (notably http://www.android.com)

I suspect that this comes from mag -- I noticed that the graphics performance of L4Android is not great, for example, even boot animation lags on L4Android.

I suspect it'll take some time to fix, so is there a way to disable mag and let l4linux takes care of the frame buffer directly?
