Pretty much, but I think on sarge at least, the amd64 version did not
even have the module compiled, so there was no way to get it to work.
At least Etch appears to have it enabled so at least it is possible to
load it manually.

Well there has always been the option of going to the console on tty2
and telling it to load the driver, and going back to the installer on
console 1 and continuing.

Well certainly expert mode install asks many more questions.  And there
is always console 2 where you can manually load a module.

I think the problem could be that most drivers are auto detected by pci
id, which may not be easy to do for the I2O stuff.  I don't actually
know how i2o devices appear on the system.  Of course there also aren't
that many people using i2o, so it may just be that no one ever bothered
to test the installer on such a system and complain about it not working
so that it could have been fixed.  After all if the installer developers
don't know it doesn't work, they can't fix it.
