hi Attilio, ...
You didn't mention the pegasos on that survey. There with a radeon 9250, it
worked fien with only the no-hardware option, while it crashed with a radeon
9800 PRO with no-hardware. (didn't test yet while removing the options).

It worked fine though on pegasos, with an usb mouse.But then the pegasos also
has ps2 keyboard and mouse support.

What for the PowerBook6,7 ? maybe this second one could be made conditional on
pegasos and on PowerBook6,7 ?
