Linux and hostap_plx : immediate lockup!

I have just moved my NetGear MA301 PLX adapter (with MA401 PCMCIA card) from my old Linux 2.4
machine into my Linux machine. The card appears OK in the lspci output:

00:0e.0 Network controller: Netgear MA301 802.11b Wireless PCI Adapter (rev 02)
        Subsystem: Netgear MA301 802.11b Wireless PCI Adapter
        Control: I/O+ Mem+ BusMaster- SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR+
        Status: Cap- 66MHz- UDF- FastB2B+ ParErr- DEVSEL=medium >TAbort- <TAbort- <MAbort- >SERR-
        Interrupt: pin A routed to IRQ 5
        Region 1: I/O ports at 1000 [size=128]
        Region 2: Memory at e800a000 (32-bit, non-prefetchable) [size=4K]
        Region 3: I/O ports at 1080 [size=64]

However, the entire PC locks up immediately as soon as the hostap_plx driver loads. These are the
"version magic" options for the hostap_plx.ko module:

vermagic: preempt mod_unload PENTIUMIII 4KSTACKS 

Has anyone managed to use the hostap_plx module with, please? Are if so, is anyone using
4KSTACKS or preempt?

I don't see why the card should suddenly have stopped working, and it *is* visible on the PCI bus.
