Kernel debug messages for Linksys eth0 driver connected to 10/100 switch.

I'm still trying to get my Linksys card to work with anything other
than the driver shipped with the card (keep in mind this problem only
exists with my 10/100 switch). I grabbed a brain and realized the most
useful thing would be to enable a higher debug level. After looking
through the driver source it looked like anything greater than 1 would
be helpful, so I loaded the driver with debug=2. Then I did "ifconfig
eth0 up". This is what I got:

[...this is where I loaded the module..]

[...repeat until ifconfig eth0 down...]

It looks like the device is continuously generating a link status
interrupt, and the driver is trying to switch to 100baseTx-FD (which
should work, but obviously is failing). This mirrors what I actually
see on the card, the link light and the FD light are blinking
consistently.

Now the 0.90f modified driver I get from Linksys actually successfully
negotiates 100baseTx-FD, so the kernel driver is starting on the right
path, but somehow the link is not occurring. Does anyone have any
bright ideas as to when/where the problem might be?
