Rebuild the kernel with the other stack size? What's the big deal with
that? Does RHEL not offer that option in their kernel source?

Low point? When was it ever good? Perhaps back when the original
Orinoco Gold Card and Prism chipsets were popular, three years ago?
It's been on a long downhill slide, driven by clueless manufacturers.
The main reason to avoid ndiswrapper is to financially penalize the bad
manufacturers who don't release drivers for all OS's. But they don't
really appear to care, anyway...

But very difficult to match up Vendor names with chipsets. Standing in
a typical computer store, staring at boxes, noticing that there's now a
new "rev 04" of some stupid card that had the right chipset in it three
revisions ago, and that's the latest information on the web... is a
