Firefox 4 on pandaboard (Ubuntu 10.10)

I got pandaboard to improve ARM code on Firefox. Pandaboard uses TI OMAP4 (Dual-core Cortex-A9 and PowerVR SGX 540), so it is the most powerful ARM board.

This data is sunspider benchmark on Firefox 4 on pandaboard. BTW, my Android phone (HTC Desire HD) is 2800ms.

Although I have already landed ARM optimized NSS code (for crypto) into cvs.mozilla.org, it won't used by Firefox 4 or 5. It is for NSS trunk (NSS version 4). But I am investigate ARM specific optimization for Firefox 5.
