I've had nothing but good results recently under AC3 with many Radeons
and even a Rage 128, including reasonable stability with 3D apps.

The older Mac64 cards may be an entirely different story, however,
given your experiences.

Rergardless, here's  what I think happened to make the "atimisc" driver
fail on Alpha:

Here we see the "./configure" line that starts the build:

I've not been able to figure out where the "alphaev56-*" is always
coming from, as I know I'm building on an EV6 machine...

Next comes:

> checking host system type... alphaev56-unknown-linux-gnu

OK, this prolly sets the "host_cpu" var in the script to "alphaev56".

And finally we see:

> checking whether to include PIO support... no, MMIO

And that's the crux, according to the messages that later appear in
Xorg.0.log.

Now, looking at ./configure we see:

And there it is - it should be "x86_64|amd64|alpha*|ia64" instead, to catch
any subarchs that show up in this field.

Anyone for a rebuild? :-) :-)
