I've got hold of the datasheet. It's a generic PCI to ISA bridge indeed.

I'm still thinking about what driver to create.. A driver that
emulates a PCMCIA controller is a knightmare, but so is an ethernet driver
for this setup.

The 2.4.x kernel has support for the wireless card itself, but in a PCMCIA
context. Creating a ethernet driver creates a lot of duplicate code.

I don't call it support. The drivers are ancient, pcmcia-cs on their site
is a 1.5 year old version, and the driver itself doesn't work. Making it
work would require a large amount of code change to their driver, so it's
better to start from scratch.
