Nope, it was a PCI problem -- moved the card to slot 1 (bus 0) and it
works fine now... however, my second ethernet card, which now resides
in slot 5 (bus 1 card 2) now doesn't function properly...
(it *seems* to work, but ceases to function after a short while
saying "no interrupts being serviced" or something similar).

Tried both 2.4.0test11 and 2.2.17 & 2.2.18pre21 w/ Michel Lanners patches;
none of them solved the problem. I will check the 2.4 bitkeeper kernel,
though.
