I have it here:
http://ns1.xcllnt.net/~marcel/machines/ia64/altix/ALTIX
Don't mind the modules -- they don't work :-)
There's another piece of information that I forgot to relay:
The serial console is implemented by SAL on Altix hardware,
so you need the following environment variable to tell the
kernel (and the uart(4) driver in particular) to use the SAL
hardware:
hw.uart.console=3Ddt:sgisn
I copied the loader that I'm using here:
http://ns1.xcllnt.net/~marcel/machines/ia64/altix/loader.efi
As for the kernel: make sure it's linked at 0xe000003400000000.
