I've read through the lists, and have found a coule of suggestions 
for the:

xi0: device timetout

Error.  I've tried the PCIC_ISA_INTR_ALLOC_MASK option in the kernel
and it does not help.

Any suggestions on how I can get my Laptops working with this
NIC would be helpful.

My systems: Sony PCG-F370 laptop (two of them)
The Card: Xircom RealPort Eathernet 10/100 RE-100 (PCCARD, not Cardbus)

Here are the messages I'm getting from the system: (please excuse any
typos, this was done my hand since I can't conect to the system over the
net.)

Looking at dmesg there are only three things attached to irq 9:

  uhci0: interrupting at irq 9
  cbb0: interrupting at irq 9
  cbb1: interrupting at irq 9

But looking at the "device vendor product pin PIRQ IRQ stage listing:

I've tried turning off USB, but the kernel hangs with out USB support on
boot. Plug and play OS is set to NO.

Here is the option in the kernel config:

options PCIC_ISA_INTR_ALLOC_MASK=0x0008

The laptop has its serial and parallel ports turned off.

The xi0 device configured correctly, but can't connect to the network. (It
even lights up on the card and the hub.)

Any help would be apricheated!

Thanks!
