[ltp] 760E, Xircom RBEM and kernel 2.4.x ;-(

I guess I must send out a cry for help. I have a TP 760E and a Xircom
RBEM56G-100 (RealPort CardBus Ethernet 10/100 + Modem 56) card.
After a little bit of work, the combo worked fine with W98 (network and
modem), it also works fine with 2.2.19 (only network) on Debian woody.
But I'm completely unable to get it working with any 2.4.x kernel (I'm
using the kernel pcmcia driver, i.e yenta_socket, haven't yet tried to
replace them with David Hinds).
While I tried several things with different results, the main problem
seems to be the problem that yenta_socket is unable to find an interrupt
for the CardBus bridges, i.e. the problem is only with the TP760E and
not with the Xircom.
I also tried 'append="pci=biosirq"' in /etc/lilo.conf, but it didn't
help.
Perhaps some ThinkPad wizards could look at the following report and see
if they have some more insight. I have much more configuration data and
logs at hand, so please just tell me if something is missing.
Without any card inserted, the startup log of the pcmcia system looks
like this (with 2.4.13):

Compared with the output of 2.2.19:

(for the curious Debian users, I have simply patched /etc/init.d/pcmcia
to load either yenta_socket or i82365, depending on if we're running
2.4.x or 2.2.x).
This very much looks like 2.4.13 is no longer able to guess the irq (10)
of the card, and this is probably the cause of all following problems.
When I now insert the Xircom card, the system will find the card, and
load up the xircom_cb module (and setup eth0), but to no avail, i.e. I
won't be able to ping or whatelse, since the card has no valid interrupt
assigned to:

Cf. with 2.2.19, where the card (net and modem) gets assigned IRQ 5, and
works just fine afterwards:

didn't help the kernel to find the correct IRQs. Instead, the hint about
using biosirq just goes away without any new help:
