CardBus bridge and wireless card plugged into it use same IRQ: Correct?

Hi All

Here is the output of lspci -v:

0001:10:1a.0 CardBus bridge: Texas Instruments PCI1410 PC card Cardbus Controller (rev 02)
        Flags: bus master, medium devsel, latency 168, IRQ 58
        Memory at a0000000 (32-bit, non-prefetchable) [size=4K]
        Bus: primary=10, secondary=11, subordinate=14, sec-latency=176

0001:11:00.0 Network controller: RaLink Ralink RT2500 802.11 Cardbus Reference Card (rev 01)
        Subsystem: Unknown device 1948:3c00
        Flags: bus master, slow devsel, latency 0, IRQ 58
        Memory at f3000000 (32-bit, non-prefetchable) [size=8K]
        Capabilities: <available only to root>

The above details the fact (or better: I hope it's a fact :) that
"Ralink RT2500" (a wi-fi chip) is connected to the PCMCIA slot
("CardBus bridge") of a Titanium IV ..

Logic might suggest the connector (the "bridge") can/must use the same
interrupt as the wireless card that is connected to the former, but
I'm not sure on it. So if someone with more knowledge could enlighten
me a bit.

Oh yes: And this might be of interest, too:

ra0 is the wi-fi card, as I hope ... 

Thanks in anticipation ...
