The compaq WL200's ships with a CIS that doesn't request an IRQ from the
PCMCIA-CS.
All drivers will load ... things seem to be there like ...
"ifconfig -a" shows the wlan0 device etc. but nothings works ... right?
"cat /proc/interrupts" doesn't show prism2 having an irq huh?

then you need to create a substitute CIS for the card (or get Mark to
release
the prism2dl utility again and try to upload a new CIS to the card) using
the
dump_cis and pack_cis debug utilities from pcmcia-cs package.

While I've been using Linux for a long time, I can't claim to be a hardware
expert, but I *think* everything is OK with the IRQs

I was originally concerned that it was an IRQ issue, as lspci reports
an IRQ of 0 for the card:

01:06.0 PCMCIA bridge: Cirrus Logic CL 6729 (rev 07)
        Control: I/O+ Mem+ BusMaster- SpecCycle- MemWINV- VGASnoop- ParErr-
\
             Stepping+ SERR- FastB2B-
        Status: Cap- 66Mhz- UDF- FastB2B- ParErr- DEVSEL=slow >TAbort+ \
             <TAbort- <MAbort- >SERR- <PERR-
        Interrupt: pin A routed to IRQ 0
        Region 0: I/O ports at 5800

However, the card is configured to "use PCI interrupts," not ISA interrupts
so I think that this is OK. I've poked around pretty extensively in the
computer's BIOS, and there isn't really anything I can do to control the
IRQ that this card is getting. I tried manually setting an IRQ with setpci
as a lark, but it didn't seem to do anything.

irq_mode=0 (ISA interrupts) immediately freezes the machine David
Hinds (the author of pcmcia-cs) assured me that this particular card
will need PCI interrupts (irq_mode=1).

The machine does have ISA slots, so I may have to give that a try.
I just don't want to spend another $200US for a card and not have
it work. I'll check to see if there is a true PCI airlancer.

Well, the messages output point to a memory probe failure. This usually
means that one is searching the wrong memory, but I've tried so many ranges
that it very well could actually be a PCI bus timing issue. I've tried
many different settings, but the attached is demonstrative of what I
see:

Thanks for the suggestions!
