In my case, it's because the kernel's pcmcia/cardbus and 3c59x
drivers don't work nearly as well as David Hinds' pcmcia-cs package,
to the point that I rarely even bother testing the kernel drivers.
Disregarding problems with cardbus bridges on some laptops, I've had the
following problems with kernel-based pcmcia/cardbus and 3c59x:
1. Naming confusion and incompatibilities with the pcmcia-cs
cardmgr. I was able to use the kernel's drivers with pcmcia-cs
between (roughly) 2.3.48 and 2.3.99-pre1. Later, perhaps
in 2.3.99-pre9, I tested the kernel drivers again. 3c59x
did recognize my 3c575_cb card, but cardmgr failed to `up' it,
apparently due to some naming confusion (eth0 vs 3c575_cb).
A manual ifup did work, but requiring manual intervention is
not acceptable.
2. In 2.4.0-test3-pre2, both vanilla and with your final 3c59x patch,
vortex_probe1() fails which prevents the module from loading at all.
Here's a excerpt from my /var/log/messages:
