(updated) irq assignment issue: TI 1410 + Serverworks

[Mustafa C. Kuscu]

Is this a known issue with TI-1410 and the Serverworks chipset, on kernel
2.4?

The `lspci -vvv` for the bridge is as follows:
00:07.0 CardBus bridge: Texas Instruments PCI1410 PC card Cardbus
Controller (rev 01)
        Subsystem: SCM Microsystems: Unknown device 3000
        Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop-
ParErr- Stepping- SERR- FastB2B-
        Status: Cap+ 66Mhz- UDF- FastB2B- ParErr- DEVSEL=medium >TAbort-
<TAbort- <MAbort- >SERR- <PERR-
        Latency: 168, cache line size 08
        Interrupt: pin A routed to IRQ 0
        Region 0: Memory at 20000000 (32-bit, non-prefetchable) [size=4K]

I have a working TI-1410 on another machine, on IRQ3 (non-Serverworks
chipset):

01:01.0 CardBus bridge: Texas Instruments PCI1410 PC card
Cardbus Controller (rev 01)
        Subsystem: SCM Microsystems: Unknown device 3000
        Flags: bus master, medium devsel, latency 168, IRQ 3
        Memory at 1ff01000 (32-bit, non-prefetchable) [size=4K]
        Bus: primary=01, secondary=02, subordinate=05, sec-latency=176
        Memory window 0: 20000000-203ff000 (prefetchable)
        Memory window 1: 20400000-207ff000
        I/O window 0: 00004000-000040ff
        I/O window 1: 00004400-000044ff
        16-bit legacy interface ports at 0001
