No! I guess that's.. good news? :)
I really didn't expect this, and was about to report it as a potential
hardware problem to IBM after struggling with it for days: also
because the card now sometimes unexpectedly drops out in Windows XP
too, the little I've used it (Cisco util shows the MAC address
suddenly as 00:00:00:00:00:00). I'll guess I'll put that down to XP
not hardware and await your verdict.
Unless of course we both have the same hardware problem under high
load...
Thanks for continuing help with this Fabrice.
