Well, to work as well as on x86, Linux on ARM would need two things : standard and well-documented hardware, and easy device reflashing.

Several major phone manufacturers are opening up their bootloaders, so we're getting there on the reflashing front. But as for standard and well-documented hardware... NVidia, TI, and Qualcomm each do their own thing in their little corner, and if it has not changed since the last time I checked, the only resource which they publicly provide to OS developers are binary Android drivers.

Probably someone will end up reverse engineering those or shoehorning them on Linux at some point, and we'll get something not very reliable and efficient like Nouveau, but for every piece of ARM hardware out there. The future of Linux on ARM, or every other alternative OS for that matter, does not look bright.

Samsung Puts Out New Open-Source ARM DRM Driver

"Samsung has published the code to a new open-source DRM driver for its EXYNOS4210 System-On-a-Chip. The EXYNOS4210 has impressive 3D graphics capabilities, uses the dual-core ARM Cortex A9 processor, and is used in various smart-phones. The Samsung Galaxy S II is one of the smart-phones using the Exynos 4210 SoC. Samsung is hoping to push this DRM driver into the mainline Linux kernel."

Texas Instruments Has New Open-Source Driver

"While Texas Instruments released an open-source driver last year for the Linux kernel within the DRM area (the TILER driver), it didn't make it into the mainline tree for the lack of open-source user-space applications/drivers that could take advantage of it, i.e. the usual ARM graphics mess. Yesterday, however, Texas Instruments released a new open-source DRM driver for their OMAP platforms."

I'm sorry about that, I got it wrong.

"Texas Instruments OMAP (Open Multimedia Application Platform) is a category of proprietary system on chips (SoCs) for portable and mobile multimedia applications developed by Texas Instruments. OMAP devices generally include a general-purpose ARM architecture processor core plus one or more specialized co-processors."

OMAP platform SoCs apparently have ARM cores.

OMAP 4 - The 4th generation OMAPs, OMAP4430, 4460 and 4470 all use dual-core ARM Cortex-A9s. All OMAP 4 comes with an IVA3 multimedia hardware accelerator with a programmable DSP that enables 1080p Full HD and multi-standard video encode/decode.

OMAP 5 - The 5th generation OMAP, OMAP 5 SoC uses a dual-core ARM Cortex-A15 CPU with two additional ARM Cortex-M4 cores to offload the A15s in less computionally intensive tasks to increase power efficiency, two PowerVR SGX544MP graphics cores and a dedicated TI 2D BitBlt graphics accelerator, a multi-pipe display sub-system and a signal processor. They respectively support 24 and 20-megapixel cameras for front and rear 3D HD video recording. The chip also supports up to 8GB of dual channel DDR3 memory, output to four HD 3D displays and 3D HDMI 1.4 video output. OMAP 5 also includes 3 USB 2.0 ports and a SATA 2.0 controller.

Wow.
