I think you're using the i82365 driver in 2.4.27 but the yenta driver in 2.6. 
Can you try using i82365 in 2.6?

It looks like the CardBus bridge devices (00:13.0 and 00:13.1) claim to be
using PCI interrupts INTA and INTB, but we didn't find those in the ACPI _PRT. 
That might be a BIOS bug, but I don't think it's the root cause here.

My PCMCIA/CardBus understanding is meager, but I think the bridge itself and
devices behind the bridge (e.g., your NIC) can use different interrupts.  Your
bridge claims to be generating interrupts on INTA and INTB (and we don't know
what they're connected to), but I think the NIC is using IRQ 3.  My guess is
that the bridge is connecting the CINT# wire from the NIC directly to the IRQ 3
input on an interrupt controller.

I don't know why yenta can't deal with this, but I wonder if i82365 can.
