I recall somebody reported, a month or a few ago, that he had 3Com
Cardbus ethernet-adapter, which needed to be inserted, removed and
then inserted again before network was set up properly. I didn't
follow that thread and wasn't able to find it now that I have exactly
the same problem. Did anybody have any solution to this?

I have experienced this problem with every kernel I have tried this
card with (2.4.9, 2.4.1[0-3]ac, 2.4.15pre[67]). When I boot my Dell
Latitude with the card (3CCFE575BT-D) inserted, it _does_ detect a
card in the socket:

Nov 21 00:01:00 puck cardmgr[188]: initializing socket 1
Nov 21 00:01:00 puck cardmgr[188]: socket 1: 3Com 3CCFE575B/3CXFE575B Fast EtherLink XL

At this point, the module 3c59x does not load. Also at this point the
adapter has 10BaseT led on, though my network is 100BaseT. 

Then I remove remove the card and insert it again:

Nov 21 00:02:07 puck kernel: cs: cb_free(bus 6)
Nov 21 00:02:07 puck cardmgr[188]: shutting down socket 1
Nov 21 00:02:07 puck /etc/hotplug/pci.agent: PCI remove event not supported
Nov 21 00:02:12 puck kernel: cs: cb_alloc(bus 6): vendor 0x10b7, device 0x5157
Nov 21 00:02:12 puck kernel: PCI: Enabling device 06:00.0 (0000 -> 0003)
Nov 21 00:02:12 puck cardmgr[188]: initializing socket 1
Nov 21 00:02:12 puck cardmgr[188]: socket 1: 3Com 3CCFE575B/3CXFE575B Fast EtherLink XL
Nov 21 00:02:12 puck /etc/hotplug/pci.agent: Modprobe and setup 3c59x for PCI slot 06:00.0
Nov 21 00:02:12 puck kernel: 3c59x: Donald Becker and others. www.scyld.com/network/vortex.html
Nov 21 00:02:12 puck kernel: 06:00.0: 3Com PCI 3CCFE575BT Cyclone CardBus at 0x4800. Vers LK1.1.16
Nov 21 00:02:12 puck kernel: PCI: Setting latency timer of device 06:00.0 to 64
Nov 21 00:02:12 puck /etc/hotplug/net.agent: invoke ifup eth0

Now it now loads 3c59x and has the 100BaseT led on, but at this point
it still does not get the network up and running. (Meaning: ifconfig
still shows only loopback-interface up.)

So, let's remove and insert again:

Nov 21 00:02:24 puck kernel: cs: cb_free(bus 6)
Nov 21 00:02:24 puck cardmgr[188]: shutting down socket 1
Nov 21 00:02:24 puck /etc/hotplug/net.agent: invoke ifdown eth0
Nov 21 00:02:24 puck /etc/hotplug/pci.agent: PCI remove event not supported
Nov 21 00:02:26 puck kernel: cs: cb_alloc(bus 6): vendor 0x10b7, device 0x5157
Nov 21 00:02:26 puck kernel: PCI: Enabling device 06:00.0 (0000 -> 0003)
Nov 21 00:02:26 puck kernel: 06:00.0: 3Com PCI 3CCFE575BT Cyclone CardBus at 0x4800. Vers LK1.1.16
Nov 21 00:02:26 puck kernel: PCI: Setting latency timer of device 06:00.0 to 64
Nov 21 00:02:26 puck cardmgr[188]: initializing socket 1
Nov 21 00:02:26 puck cardmgr[188]: socket 1: 3Com 3CCFE575B/3CXFE575B Fast EtherLink XL
Nov 21 00:02:26 puck /etc/hotplug/net.agent: invoke ifup eth0
Nov 21 00:02:26 puck /etc/hotplug/pci.agent: Modprobe and setup 3c59x for PCI slot 06:00.0
Nov 21 00:02:29 puck kernel: eth0: Setting full-duplex based on MII #0 link partner capability of 45e1.

Now everything works like a charm.

What should I look at in order to find out what's going on here?

The current kernel is 2.4.15pre7 and the hotplug-utilities are from
Debian package with versioned as 0.0.20010919-2.
