In F11, fedora base architecture raised from i386 to i586. Now F12 will be shipped for i686 processors and above.
Doing so, in one year they have lost support for the following CPU families:
Intel i386, i486, i586
National Semiconductor Geode processors
VIA C3, Ezra and Samuel Cores (my box is involved too, s**t)
AMD Geode GX
IMO one of the valuable points of open source software, among others, was the ability to inject new life into old hardware.
Here, the fedora project have lost support for many boxes in order to a gain, with their words, a "1% improvement in generic code"
I really cannot understand that.
