I absolutely agree that the lack of usably fast hardware is the biggest problem.
While installing software on the O2 is slow enough as it is, having
some kind of quality-assurance from Gentoo/MIPS in the form of
ACCEPT_KEYWORDS="mips -~mips" would definitely make installing
software on the O2 less painful. Believe me, I've been there.
Compiling some package on a 300MHz R5000 takes hours, and then you
find out that it's clearly _never_ been tested when it breaks your
entire system so you've got to start the whole process over with a
I think the future of Linux/MIPS for regular users lies with
Lemote/GDium hardware. (We're probably going to not worry about things
like Octeon, for instance, since they're so expensive.) You'll notice
that many MIPS kernel developer work for companies using MIPS in
embedded environments though.
SGI systems are cheap and available though, so I think we should make
an effort to support them. The SGI Origin 300, with quad 600 MHz
R14ks, 4 MB L2 cache each, and 4 GB RAM is quite a fast system.
Unfortunately, the port has never been finished. O300s are quite cheap
(< 300 USD) and would make excellent Linux/MIPS systems, if only the
kernel port were completed.
I hope I've answered your questions. Please let me know.
