Software used by 99% users will have alternative software which have
source code available or have 64-bit version.

Chromium 22 is much more complex than Linux 1.0
linux-1.0.tar.bz2 - 20 contributors - size 1 MB
chromium-22.0.1229.14.tar.bz2 - size 200 MB

Open source drivers are black listed by Chromium because of instability
file software_rendering_list.json:
NVIDIA cards with nouveau drivers in Linux are crash-prone
The Intel Mobile 945 Express family of chipsets is not compatible with WebGL
Intel mesa drivers are crash-prone
ATI/AMD cards with third-party drivers in Linux are crash-prone
Drivers are unreliable for Optimus on Linux

Geforce 9800 GT with nouveau has worse performance than Ivy Bridge.
Radeon 6770 with open source drivers has far worse performance than Ivy Bridge.
There is no discrete Ivy Bridge graphics card.
