Installation problem with Peabird card

Hello,

I don't manage to install a Peabird 10/100 ethernet PC card ``FP32TX'' 
which is a realtek 8139-based card, with cardbus connector.
The compilation of the modules against kernel 2.4.22 was OK (except that 
cb_shim gave an ``unresolved symbol'', but I understood from a previous 
message in this mailing list that this is somehow normal [am I correct ?])

When I insert the card: no beep is heard and no module loads.
dmesg says:
cs: cb_alloc(bus 2): vendor 0x10ec, device 0x8139
PCI: Enabling device 02:00.0 (0000 -> 0003)
8139cp: 10/100 PCI Ethernet driver v0.3.0 (Sep 29, 2002)
8139cp: pci dev 02:00.0 (id 10ec:8139 rev 10) is not an 8139C+ 
compatible chip
8139cp: Try the "8139too" driver instead.

Then I manually insmod pci-scan and rtl8139
[ I understood that these actually are the only modules I need. Am I 
right ? It seems that config.opts mentions cb_shim and cb_enabler but 
the first one gives an unresolved symbol and the second one is not found 
by insmod.]
This works fine.  dmesg shows:

  The PCI BIOS has not enabled the device at 2/0!  Updating PCI command 
0003->0007.
eth0: RealTek RTL8139C Fast Ethernet at 0x4000, IRQ 10, 00:08:a1:53:f7:f8.
PCI: Setting latency timer of device 02:00.0 to 64

Now, I setup the ethernet device:
ifconfig eth0 192.168.1.2 up
and this still works fine: the ethernet device appears in the result of 
the command ifconfig.

Now, ping 192.168.1.1 (which is a valid IP number, which works with my 
other ethernet card)
says ``Destination host unreachable''
Moreover, the ifconfig shows some errors in RX packets:
eth0      Link encap:Ethernet  HWaddr 00:08:A1:53:F7:F8 
          inet addr:192.168.1.2  Bcast:192.168.1.255  Mask:255.255.255.0

          TX packets:9 errors:0 dropped:0 overruns:0 carrier:0

          RX bytes:0 (0.0 b)  TX bytes:540 (540.0 b)

So here, I don't really know what to do.
Here is the output of the diagnostic program:
_root_# ./rtl8139-diag
rtl8139-diag.c:v2.11 4/22/2003 Donald Becker ([email protected])

I read in the ethernet Howto that errors in the ``ifconfig'' output come 
most often from IRQ problem, so here is the /proc/interrupts showing IRQ 
10 assigned to eth0...
_root_# cat /proc/interrupts

Where should I start ? What should I do to find out what the problem is 
more precisely ?
Could it be related to this message given by pci-scan ``The PCI BIOS has 
not enabled the device at 2/0! '' (but I didn't find anything related in 
the BIOS) ?

In any case, many thanks.

V.G.
