I didn't see any crashes or hangs with use_dac enabled (or rather, not 
disabled).

I haven't tried use_dac=1 with media=0x2, though. Maybe that would give 
enough traffic to crash or hang my box.

No, that suffers from the same problems.

How do these patches differ from those in 2.6.10-rc2-mm2?

Let me know if there are any other patches you want me to try.

Sadly my box won't boot, if I disable ACPI.

It seems to negotiate pretty quickly with my DSL router. Less than a 
second, I'd say. I can time it a bit more exactly, if it would help.

 From your ethtool patch, it looks like I have a 8110. I did search 
their specs for version registers, etc., but I could not see them. Where 
did you get your datasheet from for the 8110?

Thanks, bye, Rich =]
