This obviously isn't a Linksys card.

That looks like normal operation.

You missed a few lines there.  What did you mean to say?
Keep in mind that the system will be very slow if you are synchronously
logging message with debug=6!  At the very least, set /etc/syslog.conf with
a "-" in front of the log file name.

That is correct.  The PCI scan module is now required to hide kernel
differences, support hot-swap/CardBus, and handle power management.

Ahhh, you have an ADMtek Comet chip.  This chip is relatively new.  It
should work correctly with my recent drivers, but will not even be detected
with earlier Tulip drivers.

I just plugged in a CardBus card based on the very similar ADMtek Centaur
chip to send this message: it's very nearly identical to a Comet, but
packaged for CardBus.  If it work in a CardBus version, the PCI version
almost certainly works.  My laptop reports 
Found a ADMtek Centaur-C at 32/0 address 0xa0060000->0xc8034000 IRQ 10.
ADMtek Centaur-C at 32/0 command 0x7.
eth0: ADMtek Comet rev 17 at 0xc8034000, 00:00:E8:11:11:25, IRQ 10.

The only buglet is that the mii-diag values are all '0'.  I'll check that
out later.

I'll run my Comet PCI board and v92 through the normal tests tomorrow if I
get a chance.

How very '1337.
